CHAPTER 1

Orientation

1.1 – Setting the context

Before we start this module on Option Strategy, I would like to share with you a

Behavioral Finance article I read couple of years ago. The article was titled “Why

winning is addictive”.

Here is the article, authored by B.Venkatesh (a regular columnist for HBL) –

“To buy and bet on a lottery ticket – a game that you typically avoid because you

understand the odds of winning the jackpot is really low. However, if you do win the

ticket, you will be most likely tempted to buy a lottery ticket regularly thereafter!

We exhibit similar behavior when it comes to our investments as well. What drives such

behavior? As humans, our life is governed by anticipation. So, looking forward to

winning a lottery is exciting and so is realizing that expectation.

Research in neuroscience has however shown that anticipating a win is more exciting

than actual winning! Nevertheless, once you experience the excitement of winning a

lottery you feel the need to indulge. That is, your brain compels you to buy a lottery

ticket, even though you are aware of the odds of winning the second one.

This happens because we tend to use more of reflexive brain than reflective brain. The

reflective brain performs calculation that helps you analyze and think. The reflexive

brain helps you feel and is more intuitive. When you feel an urge to buy a lottery ticket,

it is your reflexive brain that is pushing you to do so. Your reflective brain is likely to tell

you that the odds of winning the jackpot for the second time are low!

Now consider trading in equity options. You know that buying calls and puts has its risk,

as options often expire worthless. Yet we may choose to buy them regularly, especially if

we have already experienced large gains from such investments, for it is the reflexive

brain in action. With trading options there is another factor at play. We know that

zerodha.com/varsity

options carry the risk of losing capital when our view on the underlying stock or the

index turns wrong.

The fact that we can lose money makes our experience of winning against such odds

even more exciting! This is not so much true of lottery because a lottery is a game of

chance while investments, we believe, require some degree of skill”

You maybe be wondering, why I chose to post the above article right at the beginning of

this module. Well, this article echoes some of my own thoughts; in fact it goes a step

further to put things in the behavioral finance context. From the many interactions that

I’ve have had with both experienced and aspiring options traders, one point is quite

common - most options traders treat options trading as a ‘hit or miss” kind of a trade.

There is always a sense of amusement when one initiates an option trade, many don’t

realize how fatal this naïve amusement can be.

Traders buy options (month after month) with a hope they would double their

investment. Trading options with such a mindset is a perfect recipe for a P&L disaster.

The bottom line is this – if you aspire to trade options, you need to do it the right way

and follow the right approach. Else you can be rest assured the gambling attitude will

eventually consume your entire trading capital and you will end up having a short, self

destructive option trading career.

zerodha.com/varsity

I do have to mention this now - the common phrase that goes like this (w.r.t options)

“limited risk, unlimited profit potential” is a silent P&L killer. Newbie traders are

disillusioned by this ‘theoretically correct’ but practically disastrous fact and thereby end

up blowing up their books, slowly and steadily. Hence I do believe that trading options

blindly without a strategy is a “dangerous but irresistible pass time” (courtesy - Pink

Floyd).

I don’t intend to scare you with this note; I’m only trying to set the context here. With

the previous module on Options Theory, I’m sure you would have realized that unlike

other topics in the markets, the science involved in Options is heavy duty. It can be quite

overwhelming, but you will have to trust me here – the only way to understand and

master options trading is by structuring your learning path with a good judicious mix of

theory and practice.

In this module, I will attempt to give you a good overview of what you really need to

know about some of the popular options strategies. Like always, I will try and stick to

the practical aspect and ignore the unwanted (and confusing) theory part.

zerodha.com/varsity

As far as I’m aware, there are close to 475 options strategies out there in the public

domain and I’m sure at least another 100 odd strategies are hidden in the proprietary

books of brokers, bankers, and traders. Given this should you know all these strategies

put up in the public domain?

Answer is a simple no.

1.2 – What should you know?

You only need to know a handful of strategies but you need to know them really well.

Once you know these strategies all you need to do is analyze the current state of markets

(or the stock) and map it with the right option strategy from your strategy quiver.

Keeping this in perspective we will discuss certain strategies.

Bullish Strategies

1. Bull Call Spread

2. Bull Put Spread

3. Call Ratio Back Spread

4. Bear Call Ladder

5. Call Butterfly

6. Synthetic Call

7. Straps

Bearish Spreads

1. Bear Call Spread

2. Bear Put Spread

5. Strip

6. Synthetic Put

Neutral Strategies

1. Long & Short Straddles

2. Long & Short Strangles

3. Long & Short Iron

Condor

4. Long & Short Butterfly

5. Box

Besides discussing the above strategies I also intend to discuss –

1. Max Pain for option writing – (some key observations and practical aspects)

2. Volatility Arbitrage employing Dynamic Delta hedging

zerodha.com/varsity

The plan is to discuss one option strategy per chapter so that there is ample clarity about

the strategy, without any mix up or confusion. This means to say we will have roughly

about 20 chapters in this module, although I suppose each chapter would not be too

lengthy. For each of the strategy I will discuss the background, implementation, payoff,

breakeven, and perhaps the right strikes to use considering the time to expiry. I also

intend to share a working excel model which would come handy if you intent to employ

the strategy.

Do note, while I will discuss all these strategies keeping the Nifty Index as reference, you

can use the same for any stock options.

Now here is the most important thing I want you to be aware of – do not expect a holy

grail in this module. None of the strategies that we discuss here in the module is sure

shot money making machine; in fact nothing is in the markets. The objective here in this

module is to ensure that we discuss few basic but important strategies, if you deploy

them right you can make money.

Think about this way – if you have a nice car and drive it properly, you can use it to

commute and ensure comfort of yourself and your family. However if you are rash with

the car, then it can be dangerous to you and everyone else around you.

Likewise these strategies make money if you use it right; if you don’t then they can

create a hole in your P&L. My job here is to help you understand these strategies (help

you learn how to drive the car) and I will also attempt to explain the best condition

under which you can use these strategies. But making sure it works for you is in your

control, this really depends on your discipline and reading of markets. Having said this,

I’m reasonably certain your application of strategies will improve as and when you

spend more ‘quality’ time in the markets.

So starting from the next chapter we focus on the Bullish strategies with the ‘Bull Call

Spread’ making its debut.

Stay tuned.

zerodha.com/varsity

CHAPTER 2

Bull Call Spread

2.1 – Background

The spread strategies are some of the simplest option strategies that a trader can

implement. Spreads are multi leg strategies involving 2 or more options. When I say

multi leg strategies, it implies the strategy requires 2 or more option transactions.

Spread strategy such as the ‘Bull Call Spread’ is best implemented when your outlook on

the stock/index is ‘moderate’ and not really ‘aggressive’. For example the outlook on a

particular stock could be ‘moderately bullish’ or ‘moderately bearish’.

Some of the typical scenarios where your outlook can turn ‘moderately bullish’ are

outlined as below –

Fundamental perspective - Reliance Industries is expected to make its Q3 quarterly

results announcement. From the management’s Q2 quarterly guidance you know that

the Q3 results are expected to be better than both Q2 and Q3 of last year. However you

do not know by how many basis points the results will be better. This is clearly the

missing part of the puzzle.

Given this you expect the stock price to react positively to the result announcement.

However because the guidance was laid out in Q2 the market could have kind of

factored in the news. This leads you to think that the stock can go up, but with a limited

upside.

Technical Perspective – The stock that you are tracking has been in the down trend

for a while, so much so that it is at a 52 week low, testing the 200 day moving average,

and also near a multi-year support. Given all this there is a high probability that the

stock could stage a relief rally. However you are not completely bullish as whatever said

and done the stock is still in a downtrend.

zerodha.com/varsity

Quantitative Perspective – The stock is consistently trading between the 1

standard

deviation both ways (+1 SD & -1 SD), exhibiting a consistent mean reverting behavior.

However there has been a sudden decline in the stock price, so much so that the stock

price is now at the 2

standard deviation. There is no fundamental reason backing the

stock price decline, hence there is a good chance that the stock price could revert to

mean. This makes you bullish on the stock, but the fact that it there is a chance that it

could spend more time near the 2

SD before reverting to mean caps your bullish

outlook on the stock.

The point here is – your perspective could be developed from any theory (fundamental,

technical, or quantitative) and you could find yourself in a ‘moderately bullish’ stance. In

fact this is true for a ‘moderately bearish’ stance as well. In such a situation you can

simply invoke a spread strategy wherein you can set up option positions in such a way

that

1. You protect yourself on the downside (in case you are proved wrong)

2. The amount of profit that you make is also predefined (capped)

3. As a trade off (for capping your profits) you get to participate in the market for a lesser

cost

The 3

point could be a little confusing at this stage; you will get clarity on it as we

proceed.

2.2 – Strategy notes

Amongst all the spread strategies, the bull call spread is one the most popular one. The

strategy comes handy when you have a moderately bullish view on the stock/index.

The bull call spread is a two leg spread strategy traditionally involving ATM and OTM

options. However you can create the bull call spread using other strikes as well.

To implement the bull call spread –

1. Buy 1 ATM call option (leg 1)

2. Sell 1 OTM call option (leg 2)

When you do this ensure –

1. All strikes belong to the same underlying

2. Belong to the same expiry series

zerodha.com/varsity

3. Each leg involves the same number of options

For example –

Date – 23

November 2015

Outlook – Moderately bullish (expect the market to go higher but the expiry around the

corner could limit the upside)

Nifty Spot – 7846

ATM – 7800 CE, premium – Rs.79/-

OTM – 7900 CE, premium – Rs.25/-

Bull Call Spread, trade set up -

1. Buy 7800 CE by paying 79 towards the premium. Since money is going out of my

account this is a debit transaction

2. Sell 7900 CE and receive 25 as premium. Since I receive money, this is a credit

transaction

3. The net cash flow is the difference between the debit and credit i.e 79 – 25 = 54.

Generally speaking in a bull call spread there is always a ‘net debit’, hence the bull call

spread is also called referred to as a ‘debit bull spread’.

After we initiate the trade, the market can move in any direction and expiry at any level.

Therefore let us take up a few scenarios to get a sense of what would happen to the bull

call spread for different levels of expiry.

Scenario 1 - Market expires at 7700 (below the lower strike price i.e ATM

option)

The value of the call options would depend upon its intrinsic value. If you recall from the

previous module, the intrinsic value of a call option upon expiry is –

Max [0, Spot-Strike]

In case of 7800 CE, the intrinsic value would be –

zerodha.com/varsity

Max [0, 7700 – 7800]

= Max [0, -100]

= 0

Since the 7800 (ATM) call option has 0 intrinsic value we would lose the entire

premium paid i.e Rs.79/-

The 7900 CE option also has 0 intrinsic value, but since we have sold/written this

option we get to retain the premium of Rs.25.

So our net payoff from this would be –

-79 + 25

= 54

Do note, this is also the net debit of the overall strategy.

Scenario 2 - Market expires at 7800 (at the lower strike price i.e the ATM

option)

I will skip the math here, but you need to know that both 7800 and 7900 would have 0

intrinsic value, therefore the net loss would be 54.

Scenario 3 - Market expires at 7900 (at the higher strike price, i.e the OTM

option)

The intrinsic value of the 7800 CE would be –

Max [0, Spot-Strike]

= Max [0, 7900 – 7800]

= 100

Since we are long on this option by paying a premium of 79, we would make a profit of –

zerodha.com/varsity

100 -79

= 21

The intrinsic value of 7900 CE would be 0, therefore we get to retain the premium

Rs.25/-

Net profit would be 21 + 25 = 46

Scenario 4 - Market expires at 8000 (above the higher strike price, i.e the

OTM option)

Both the options would have a positive intrinsic value

7800 CE would have an intrinsic value of 200, and the 7900 CE would have an intrinsic

value of 100.

On the 7800 CE we would make 200 – 79 = 121 in profit

And on the 7900 CE we would lose 100 – 25 = 75

The overall profit would be

121 – 75

= 46

To summarize –

Market Expiry

LS – IV

HS – IV

Net pay off

7700

(54)

7800

(54)

7900

100

+46

8000

200

100

+46

From this, 2 things should be clear to you –

1. Irrespective of the down move in the market, the loss is restricted to Rs.54, the

maximum loss also happens to be the ‘net debit’ of the strategy

zerodha.com/varsity

2. The maximum profit is capped to 46. This also happens to be the difference between the

spread and strategy’s net debit

We can define the ‘Spread’ as -

Spread = Difference between the higher and lower strike price

We can calculate the overall profitability of the strategy for any given expiry value. Here

is screenshot of the calculations that I made on the excel sheet –

 LS – IV - Lower Strike - Intrinsic value (7800 CE, ATM)

 PP – Premium Paid

 LS Payoff – Lower Strike Payoff

 HS-IV – Higher strike - Intrinsic Value (7900 CE, OTM)

 PR – Premium Received

 HS Payoff – Higher Strike Payoff

As you can notice, the loss is restricted to Rs.54, and the profit is capped to 46. Given

this,we can generalize the Bull Call Spread to identify the Max loss and Max profit levels

as -

zerodha.com/varsity

Bull Call Spread Max loss = Net Debit of the Strategy

Net Debit = Premium Paid for lower strike – Premium Received for higher strike

Bull Call Spread Max Profit = Spread – Net Debit

This is how the pay off diagram of the Bull Call Spread looks like –

There are three important points to note from the payoff diagram –

1. The strategy makes a loss in Nifty expires below 7800. However the loss is restricted to

Rs.54.

2. The breakeven point (where the strategy neither make a profit or loss) is achieved when

the market expires at 7854 (7800 + 54). Therefore we can generalize the breakeven point

for a bull call spread as Lower Strike + Net Debit

3. The strategy makes money if the market moves above 7854, however the maximum

profit achievable is Rs.46 i.e the difference between the strikes minus the net debit

a. 7900 – 7800 = 100

b. 100 – 54 = 46

I suppose at this stage you may be wondering why anyone would choose to implement a

bull call spread versus buying a plain vanilla call option. Well, the main reason is the

reduced strategy cost.

zerodha.com/varsity

Do remember your outlook is ‘moderately bullish’. Given this buying an OTM option is

ruled out. If you were to buy the ATM option you would have to pay Rs.79 as the option

premium and if the market proves you wrong, you stand to lose Rs.79. However by

implementing a bull call spread you reduce the overall cost to Rs.54 from Rs.79. As a

tradeoff you also cap your upside. In my view this is a fair deal considering you are not

aggressively bullish on the stock/index.

2.3 – Strike Selection

How would you quantify moderately bullish/bearish? Would you consider a 5% move on

Infosys as moderately bullish move, or should it be 10% and above? What about the

index such as Bank Nifty and Nifty 50? What about mid caps stocks such as Yes Bank,

Mindtree, Strides Arcolab etc? Well, clearly there is no one shoe fits all solution here.

One can attempt to quantify the ‘moderate-ness’ of the move by evaluating the

stock/index volatility.

Based on volatility I have devised a few rules (works alright for me) you may want to

improvise on it further - If the stock is highly volatile, then I would consider a move of 5-

8% as ‘moderate’. However if the stock is not very volatile I would consider sub 5% as

‘moderate’. For indices I would consider sub 5% as moderate.

Now consider this - you have a ‘moderately bullish’ view on Nifty 50 (sub 5% move),

given this which are the strikes to select for the bull call spread? Is the ATM + OTM

combo the best possible spread?

The answer to this depends on good old Theta!

Here are a bunch of graphs that will help you identify the best possible strikes based on

time to expiry.

zerodha.com/varsity

Before understanding the graphs above a few things to note –

1. Nifty spot is assumed to be at 8000

2. Start of the series is defined as anytime during the first 15 days of the series

3. End of the series is defined as anytime during the last 15 days of the series

4. The bull call spread is optimized and the spread is created with 300 points difference

The thought here is that the market will move up moderately by about 3.75% i.e from

8000 to 8300. So considering the move and the time to expiry, the graphs above suggest

–

1. Graph 1 (top left) - You are at the start of the expiry series and you expect the move

over the next 5 days, then a bull spread with far OTM is most profitable i.e 8600 (lower

strike long) and 8900 (higher strike short)

zerodha.com/varsity

2. Graph 2 (top right) - You are at the start of the expiry series and you expect the move

over the next 15 days, then a bull spread with slightly OTM is most profitable i.e 8200

and 8500

3. Graph 3 (bottom left) - You are at the start of the expiry series and you expect the

move in 25 days, then a bull spread with ATM is most profitable i.e 8000 and 8300. It

is also interesting to note that the strikes above 8200 (OTM options) make a loss.

4. Graph 4 (bottom right) - You are at the start of the expiry series and you expect the

move to occur by expiry, then a bull spread with ATM is most profitable i.e 8000 and

8300. Do note, the losses with OTM and far OTM options deepen.

Here are another bunch of charts; the only difference is that for the same move (i.e

3.75%) these charts suggest the best possible strikes to select assuming you are in the

half of the series.

zerodha.com/varsity

1. Graph 1 (top left) – If you expect a moderate move during the 2

half of the series,

and you expect the move to happen within a day (or two) then the best strikes to opt

are far OTM i.e 8600 (lower strike long) and 8900 (higher strike short)

2. Graph 2 (top right) - If you expect a moderate move during the 2

half of the series,

and you expect the move to happen over the next 5 days then the best strikes to opt are

far OTM i.e 8600 (lower strike long) and 8900 (higher strike short). Do note, both

Graph 1 and 2 are suggesting the same strikes, but the profitability of the strategy

reduces, thanks to the effect of Theta!

3. Graph 3 (bottom right) - If you expect a moderate move during the 2

half of the

series, and you expect the move to happen over the next 10 days then the best strikes to

opt are slightly OTM (1 strike away from ATM)

4. Graph 4 (bottom left) - If you expect a moderate move during the 2

half of the

series, and you expect the move to happen on expiry day, then the best strikes to opt

are ATM i.e 8000 (lower strike, long) and 8300 (higher strike, short). Do note, far OTM

options lose money even if the market moves up.

2.3 – Creating Spreads

Here is something you should know, wider the spread, higher is the amount of money

you can potentially make, but as a trade off the breakeven also increases.

To illustrate –

Today is 28

November, the first day of the December series. Nifty spot is at 7883,

consider 3 different bull call spreads –

Set 1 – Bull call spread with ITM and ATM strikes

Lower Strike (ITM, Long)

7700

Higher Strike (ATM, short)

7800

Spread

7800 – 7700 = 100

Lower Strike Premium Paid

296

Higher Strike Premium Received

227

Net Debit

296 – 227 = 69

Max Loss (same as net debit)

Max Profit (Spread – Net Debit)

100 – 69 = 31

Breakeven

7700 + 69 = 7769

zerodha.com/varsity

Remarks

Considering the outlook is moderately bullish,

7769 breakeven is easily achievable,

however the max profit is 31,

skewing the risk (69 pts) to reward (31 pts) ratio.

Set 2 – Bull call spread with ATM and OTM strikes (classic combo)

Lower Strike (ATM, Long)

7800

Higher Strike (ATM, short)

7900

Spread

7900 – 7800 = 100

Lower Strike Premium Paid

227

Higher Strike Premium Received

167

Net Debit

227 - 167 = 60

Max Loss (same as net debit)

Max Profit (Spread – Net Debit)

100 – 60 = 40

Breakeven

7800 + 60 = 7860

Remarks

Risk reward is better, but the breakeven is higher

Set 3 – Bull call spread with OTM and OTM strikes

Lower Strike (ATM, Long)

7900

Higher Strike (ATM, short)

8000

Spread

8000 – 7900 = 100

Lower Strike Premium Paid

167

Higher Strike Premium Received

116

Net Debit

167 - 116 = 51

Max Loss (same as net debit)

Max Profit (Spread – Net Debit)

100 – 51 = 49

Breakeven

7900 + 51 = 7951

Remarks

Risk reward is attractive, but the breakeven is higher

So the point is that, the risk reward changes based on the strikes that you choose.

However don’t just let the risk reward dictate the strikes that you choose. Do note you

can create a bull call spread with 2 options, for example - buy 2 ATM options and sell 2

OTM options.

Like other things in options trading, do consider the Greeks, Theta in particular!

zerodha.com/varsity

I suppose this chapter has laid a foundation for understanding basic ‘spreads’. Going

forward I will assume you are familiar with what a moderately bullish/bearish move

would mean, hence I would probably start directly with the strategy notes.

Key takeaways from this chapter

1. A moderate move would mean you expect a movement in the stock/index but the outlook

is not too aggressive

2. One has to quantify ‘moderate’ by evaluating the volatility of the stock/index

3. Bull Call spread is a basic spread that you can set up when the outlook is moderately

bullish

4. Classic bull call spread involves buying ATM option and selling OTM option – all

belonging to same expiry, same underlying, and equal quantity

5. The theta plays an important role in strike selection

6. The risk reward gets skewed based on the strikes you choose

CHAPTER 3

Bull Put Spread

3.1 – Why Bull Put Spread?

Similar to the Bull Call Spread, the Bull Put Spread is a two leg option strategy invoked

when the view on the market is ‘moderately bullish’. The Bull Put Spread is similar to

the Bull Call Spread in terms of the payoff structure; however there are a few differences

in terms of strategy execution and strike selection. The bull put spread involves creating

a spread by employing ‘Put options’ rather than ‘Call options’ (as is the case in bull call

spread).

You may have a fundamental question at this stage – when the payoffs from both Bull

call spread and Bull Put spread are similar, why should one choose a certain strategy

over the other?

zerodha.com/varsity

Well, this really depends on how attractive the premiums are. While the Bull Call spread

is executed for a debit, the bull put spread is executed for a credit. So if you are at a

point in the market where –

1. The markets have declined considerably (therefore PUT premiums have swelled)

2. The volatility is on the higher side

3. There is plenty of time to expiry

And you have a moderately bullish outlook looking ahead, then it makes sense to invoke

a Bull Put Spread for a net credit as opposed to invoking a Bull Call Spread for a net

debit. Personally I do prefer strategies which offer net credit rather than strategies

which offer net debit.

3.2 – Strategy Notes

The bull put spread is a two leg spread strategy traditionally involving ITM and OTM

Put options. However you can create the spread using other strikes as well.

To implement the bull put spread –

1. Buy 1 OTM Put option (leg 1)

2. Sell 1 ITM Put option (leg 2)

When you do this ensure –

1. All strikes belong to the same underlying

2. Belong to the same expiry series

3. Each leg involves the same number of options

For example –

Date – 7

December 2015

Outlook – Moderately bullish (expect the market to go higher)

Nifty Spot – 7805

Bull Put Spread, trade set up -

1. Buy 7700 PE by paying Rs.72/- as premium; do note this is an OTM option. Since

money is going out of my account this is a debit transaction

2. Sell 7900 PE and receive Rs.163/- as premium, do note this is an ITM option. Since I

receive money, this is a credit transaction

3. The net cash flow is the difference between the debit and credit i.e 163 – 72 = +91, since

this is a positive cashflow, there is a net credit to my account.

Generally speaking in a bull put spread there is always a ‘net credit’, hence the bull put

spread is also called referred to as a ‘Credit spread’.

After we initiate the trade, the market can move in any direction and expiry at any level.

Therefore let us take up a few scenarios to get a sense of what would happen to the bull

put spread for different levels of expiry.

Scenario 1 - Market expires at 7600 (below the lower strike price i.e OTM

option)

The value of the Put options at expiry depends upon its intrinsic value. If you recall from

the previous module, the intrinsic value of a put option upon expiry is –

Max [Strike-Spot, o]

In case of 7700 PE, the intrinsic value would be –

Max [7700 - 7600 – 0]

= Max [100, 0]

= 100

Since we are long on the 7700 PE by paying a premium of Rs.72, we would make

= Premium Paid – Intrinsic Value

= 100 – 72

= 28

zerodha.com/varsity

Likewise, in case of the 7900 PE option it has an intrinsic value of 300, but since we

have sold/written this option at Rs.163

Payoff from 7900 PE this would be –

163 - 300

= - 137

Overall strategy payoff would be –

+ 28 – 137

= - 109

Scenario 2 - Market expires at 7700 (at the lower strike price i.e the OTM

option)

The 7700 PE will not have any intrinsic value, hence we will lose all the premium that

we have paid i.e Rs.72.

The 7900 PE’s intrinsic value will be Rs.200.

Net Payoff from the strategy would be –

Premium received from selling 7900PE - Intrinsic value of 7900 PE – Premium lost on

7700 PE

= 163 – 200 – 72

= - 109

Scenario 3 - Market expires at 7900 (at the higher strike price, i.e ITM

option)

The intrinsic value of both 7700 PE and 7900 PE would be 0, hence both the potions

would expire worthless.

Net Payoff from the strategy would be –

zerodha.com/varsity

Premium received for 7900 PE - Premium Paid for 7700 PE

= 163 – 72

= + 91

Scenario 4 - Market expires at 8000 (above the higher strike price, i.e the

ITM option)

Both the options i.e 7700 PE and 7900 PE would expire worthless, hence the total

strategy payoff would be

Premium received for 7900 PE - Premium Paid for 7700 PE

= 163 – 72

= + 91

To summarize –

From this analysis, 3 things should be clear to you –

1. The strategy is profitable as and when the market moves higher

2. Irrespective of the down move in the market, the loss is restricted to Rs.109, the

maximum loss also happens to be the difference between “Spread and net credit’ of

the strategy

3. The maximum profit is capped to 91. This also happens to be the net credit of the

strategy.

We can define the ‘Spread’ as -

Spread = Difference between the higher and lower strike price

zerodha.com/varsity

We can calculate the overall profitability of the strategy for any given expiry value. Here

is screenshot of the calculations that I made on the excel sheet –

 LS – IV --- Lower Strike - Intrinsic value (7700 PE, OTM)

 PP --- Premium Paid

 LS Payoff --- Lower Strike Payoff

 HS-IV --- Higher strike - Intrinsic Value (7900 PE, ITM)

 PR --- Premium Received

 HS Payoff --- Higher Strike Payoff

As you can notice, the loss is restricted to Rs.109, and the profit is capped to Rs.91.

Given this, we can generalize the Bull Put Spread to identify the Max loss and Max profit

levels as -

Bull PUT Spread Max loss = Spread – Net Credit

Net Credit = Premium Received for higher strike – Premium Paid for lower strike

Bull Put Spread Max Profit = Net Credit

This is how the pay off diagram of the Bull Put Spread looks like –

zerodha.com/varsity

There are three important points to note from the payoff diagram –

1. The strategy makes a loss if Nifty expires below 7700. However the loss is restricted to

Rs.109.

2. The breakeven point (where the strategy neither make a profit or loss) is achieved when

the market expires at 7809. Therefore we can generalize the breakeven point for a Bull

Put spread as Higher Strike - Net Credit

3. The strategy makes money if the market moves above 7809, however the maximum

profit achievable is Rs.91 i.e the difference between the Premium Received for ITM PE

and the Premium Paid for the OTM PE

1. Premium Paid for 7700 PE = 72

2. Premium Received for 7900 PE = 163

3. Net Credit = 163 – 72 = 91

3.3 – Other Strike combinations

Remember the spread is defined as the difference between the two strike prices. The

Bull Put Spread is always created with 1 OTM Put and 1 ITM Put option, however the

strikes that you choose can be any OTM and any ITM strike. The further these strikes

are the larger the spread, the larger the spread the larger is possible reward.

Let us take some examples considering spot is at 7612 –

zerodha.com/varsity

Breakeven (Higher Strike – Net Credit)

7800 – 158 = 7642

Higher Strike (ITM, short)

7800 – 7500 = 300

Lower Strike Premium Paid

Higher Strike Premium Received

Max Loss (Spread – Net Credit)

300 – 136 = 164

Max Profit (Net Credit)

136

Breakeven (Higher Strike – Net Credit)

7800 – 136 = 7664

zerodha.com/varsity

So the point here is that, you can create the spread with any combination of OTM and

ITM option. However based on the strikes that you choose (and therefore the spread you

create), the risk reward ratio changes. In general, if you have a high conviction on a

‘moderately bullish’ view then go ahead and create a larger spread; else stick to a smaller

spread.

Key takeaways from this chapter

1. The Bull Put Spread is an alternative to the Bull Call Spread. Its best executed when the

outlook on the market is ‘moderately bullish’

2. Bull Put Spread results in a net credit

3. The Bull Put Spread is best executed when the market has cracked, put premiums are

high, the volatility is on the higher side, and you expect the market to hold up (without

cracking further)

4. The Bull Put strategy involves simultaneously buying a OTM Put option and selling a

ITM Put option

5. Maximum profit is limited to the extent of the net credit

6. Maximum loss is limited to the Spread minus Net credit

7. Breakeven is calculated as Higher Strike – Net Credit

8. One can create the spread by employing any OTM and ITM strikes

9. Higher the spread, higher the profit potential, and higher the breakeven point.

CHAPTER 4

Call Ratio Back Spread

4.1 – Background

The Call Ratio Back Spread is an interesting options strategy. I call this interesting

keeping in mind the simplicity of implementation and the kind of pay off it offers the

trader. This should certainly have a spot in your strategy arsenal. The strategy is

deployed when one is out rightly bullish on a stock (or index), unlike the bull call spread

or bull put spread where one is moderately bullish.

At a broad level this is what you will experience when you implement the Call Ratio Back

Spread-

1. Unlimited profit if the market goes up

2. Limited profit if market goes down

3. A predefined loss if the market stay within a range

In simpler words you can get to make money as long as the market moves in either

direction.

zerodha.com/varsity

Usually, the Call Ratio Back Spread is deployed for a ‘net credit’, meaning money flows

into your account as soon as you execute Call Ratio Back Spread. The ‘net credit’ is what

you make if the market goes down, as opposed to your expectation (i.e market going up).

On the other hand if the market indeed goes up, then you stand to make an unlimited

profit. I suppose this should also explain why the call ratio spread is better than buying a

plain vanilla call option.

So let’s go ahead and figure out how this works.

4.2 – Strategy Notes

The Call Ratio Back Spread is a 3 leg option strategy as it involves buying two

OTM call option and selling one ITM Call option. This is the classic 2:1 combo. In fact

the call ratio back spread has to be executed in the 2:1 ratio meaning 2 options bought

for every one option sold, or 4 options bought for every 2 option sold, so on and so forth.

Let take an example - assume Nifty Spot is at 7743 and you expect Nifty to hit 8100 by

the end of expiry. This is clearly a bullish outlook on the market. To implement the Call

Ratio Back Spread -

zerodha.com/varsity

1. Sell one lot of 7600 CE (ITM)

2. Buy two lots of 7800 CE (OTM)

Make sure –

1. The Call options belong to the same expiry

2. Belongs to the same underlying

3. The ratio is maintained

The trade set up looks like this –

1. 7600 CE, one lot short, the premium received for this is Rs.201/-

2. 7800 CE, two lots long, the premium paid is Rs.78/- per lot, so Rs.156/- for 2 lots

3. Net Cash flow is = Premium Received – Premium Paid i.e 201 – 156 = 45 (Net Credit)

With these trades, the call ratio back spread is executed. Let us check what would

happen to the overall cash flow of the strategies at different levels of expiry.

Do note we need to evaluate the strategy payoff at various levels of expiry as the strategy

payoff is quite versatile.

Scenario 1 – Market expires at 7400 (below the lower strike price)

We know the intrinsic value of a call option (upon expiry) is –

Max [Spot – Strike, 0]

The 7600 would have an intrinsic value of

Max [7400 – 7600, 0]

= 0

Since we have sold this option, we get to retain the premium received i.e Rs.201

The intrinsic value of 7800 call option would also be zero; hence we lose the total

premium paid i.e Rs.78 per lot or Rs.156 for two lots.

Net cash flow would Premium Received – Premium paid

zerodha.com/varsity

= 201 – 156

= 45

Scenario 2 – Market expires at 7600 (at the lower strike price)

The intrinsic value of both the call options i.e 7600 and 7800 would be zero, hence both

of them expire worthless.

We get to retain the premium received i.e Rs.201 towards the 7600 CE however we lose

Rs.156 on the 7800 CE resulting in a net payoff of Rs.45.

Scenario 3 – Market expires at 7645 (at the lower strike price plus net

credit)

You must be wondering why I picked the 7645 level, well this is to showcase the fact that

the strategy break even is at this level.

The intrinsic value of 7600 CE would be –

Max [Spot – Strike, 0]

= [7645 – 7600, 0]

= 45

Since, we have sold this option for 201 the net pay off from the option would be

201 – 45

= 156

On the other hand we have bought two 7800 CE by paying a premium of 156. Clearly the

7800 CE would expire worthless hence, we lose the entire premium.

Net payoff would be –

156 – 156

zerodha.com/varsity

= 0

So at 7645 the strategy neither makes money or loses any money for the trader, hence

7645 is treated as a breakeven point for this trade.

Scenario 4 – Market expires at 7700 (half way between the lower and higher

strike price)

The 7600 CE would have an intrinsic value of 100, and the 7800 would have no intrinsic

value.

On the 7600 CE we get to retain 101, as we would lose 100 from the premium received of

201 i.e 201 – 100 = 101.

We lose the entire premium of Rs.156 on the 7800 CE, hence the total payoff from the

strategy would be

= 101 – 156

= - 55

Scenario 5 – Market expires at 7800 (at the higher strike price)

This is an interesting market expiry level, think about it –

1. At 7800 the 7600 CE would have an intrinsic value of 200, and hence we have to let go of

the entire premium received i.e 201

2. At 7800, the 7800 CE would expire worthless hence we lose the entire premium paid for

the 7800 CE i.e Rs.78 per lot, since we have 2 of these we lose Rs.156

So this is like a ‘double whammy’ point for the strategy!

The net pay off for the strategy is –

Premium Received for 7600 CE – Intrinsic value of 7600 CE – Premium Paid for 7800

= 201 – 200 - 156

zerodha.com/varsity

= -155

This also happens to be the maximum loss of this strategy.

Scenario 6 – Market expires at 7955 (higher strike i.e 7800 + Max loss)

I’ve deliberately selected this strike to showcase the fact that at 7955 the strategy

breakeven!

But we dealt with a breakeven earlier, you may ask?

Well, this strategy has two breakeven points – one on the lower side (7645) and another

one on the upper side i.e 7955.

At 7955 the net payoff from the strategy is –

Premium Received for 7600 CE – Intrinsic value of 7600 CE + (2* Intrinsic value of

7800 CE) – Premium Paid for 7800 CE

= 201 – 355 + (2*155) – 156

= 201 – 355 + 310 – 156

= 0

Scenario 7 – Market expires at 8100 (higher than the higher strike price,

your expected target)

The 7600 CE will have an intrinsic value of 500, and the 7800 CE will have an intrinsic

value of 300.

The net payoff would be –

Premium Received for 7600 CE – Intrinsic value of 7600 CE + (2* Intrinsic value of

7800 CE) – Premium Paid for 7800 CE

= 201 – 500 + (2*300) – 156

= 201 – 500 + 600 -156

zerodha.com/varsity

= 145

Here are various other levels of expiry, and the eventual payoff from the strategy. Do

note, as the market goes up, so does the profits, but when the market goes down, you

still make some money, although limited.

4.3 – Strategy Generalization

Going by the above discussed scenarios we can make few generalizations –

 Spread = Higher Strike – Lower Strike

 Net Credit = Premium Received for lower strike – 2*Premium of higher strike

 Max Loss = Spread – Net Credit

 Max Loss occurs at = Higher Strike

 The payoff when market goes down = Net Credit

 Lower Breakeven = Lower Strike + Net Credit

 Upper Breakeven = Higher Strike + Max Loss

Here is a graph that highlights all these important points –

zerodha.com/varsity

Notice how the payoff remains flat even when the market goes down, the maximum loss

at 7800, and the way the payoff takes off beyond 7955.

4.4 – Welcome back the Greeks

I suppose you are familiar with these graphs by now. The following graphs show the

profitability of the strategy considering the time to expiry and therefore these graphs

help the trader select the right strikes.

zerodha.com/varsity

Before understanding the graphs above, note the following –

1. Nifty spot is assumed to be at 8000

2. Start of the series is defined as anytime during the first 15 days of the series

3. End of the series is defined as anytime during the last 15 days of the series

4. The Call Ratio Back Spread is optimized and the spread is created with 300 points

difference

The thought here is that the market will move up by about 6.25% i.e from 8000 to 8500.

So considering the move and the time to expiry, the graphs above suggest –

1. Graph 1 (top left) and Graph 2 (top right) - You are at the start of the expiry series

and you expect the move over the next 5 days (and 15 days in case of Graph 2), then a

Call Ratio Spread with 7800 CE (ITM) and 8100 CE (OTM) is the most

profitable wherein you would sell 7800 CE and buy 2 8100 CE. Do note - even though

zerodha.com/varsity

you would be right on the direction of movement, selecting other far OTM strikes call

options tend to lose money

2. Graph 3 (bottom left) and Graph 4 (bottom right) - You are at the start of the

expiry series and you expect the move in 25 days (and expiry day in case of Graph 3),

then a Call Ratio Spread with 7800 CE (ITM) and 8100 CE (OTM) is the most profitable

wherein you would sell 7800 CE and buy 2 8100 CE.

You must be wondering that the selection of strikes is same irrespective of time to

expiry. Well yes, in fact this is the point – Call ratio back spread works best when you

sell slightly ITM option and buy slightly OTM option when there is ample time to

expiry. In fact all other combinations lose money, especially the ones with far OTM

options and especially when you expect the target to be achieved closer to the expiry.

Here are another bunch of charts; the only difference is that the move (i.e 6.25%) occurs

during the 2

half of the series -

zerodha.com/varsity

1. Graph 1 (top left) & Graph 2 (top right) – If you expect the move during the 2

half

of the series, and you expect the move to happen within a day (or within 5 days,

graph 2) then the best strikes to opt are deep ITM and slightly ITM i.e 7600 (lower

strike short) and 7900 (higher strike long). Do note, this is not the classic combo of an

ITM + OTM spread, instead this is an ITM and ITM spread! In fact all other

combinations don’t work.

2. Graph 3 (bottom right) & Graph 4 (bottom left) - If you expect the move during

the 2

half of the series, and you expect the move to happen within 10 days (or on

expiry day, graph 4) then the best strikes to opt are deep ITM and slightly ITM i.e

7600 (lower strike short) and 7900 (higher strike long). This is similar to what graph 1

and graph 2 suggest.

Again, the point to note here is besides getting the direction right, the strike selection is

the key to the profitability of this strategy. One needs to be diligent enough to map the

time to expiry to the right strike to make sure that the strategy works in your favor.

What about the effect of volatility on this strategy? Well, volatility plays a key role here,

have a look at the image below –

zerodha.com/varsity

There are three colored lines depicting the change of “net premium” aka the strategy

payoff versus change in volatility. These lines help us understand the effect of increase

in volatility on the strategy keeping time to expiry in perspective.

1. Blue Line – This line suggests that an increase in volatility when there is ample time to

expiry (30 days) is beneficial for the Call ratio back spread. As we can see the strategy

payoff increases from -67 to +43 when the volatility increase from 15% to 30%. Clearly

this means that when there is ample time to expiry, besides being right on the direction

of stock/index you also need to have a view on volatility. For this reason, even though

I’m bullish on the stock, I would be a bit hesitant to deploy this strategy at the start of the

series if the volatility is on the higher side (say more than double of the usual volatility

reading)

2. Green line - This line suggests that an increase in volatility when there are about 15

days time to expiry is beneficial, although not as much as in the previous case. As we can

see the strategy payoff increases from -77 to -47 when the volatility increase from 15% to

30%.

3. Red line – This is an interesting, counter intuitive outcome. When there are very few

days to expiry, increase in volatility has a negative impact on the strategy! Think about it,

increase in volatility when there are few days to expiry enhances the possibility of the

option to expiry OTM, hence the premium decreases. So, if you are bullish on a stock /

index with few days to expiry, and you also expect the volatility to increase during this

period then thread cautiously.

Download the Call Ratio Back spread Excelsheet.

Key takeaways from this chapter

1. The Call Ratio Backspread is best executed when your outlook on the stock/index is

bullish

2. The strategy requires you to sell 1 ITM CE and buy 2 OTM CE, and this is to be executed

in the same ratio i.e for every 1 sold option, 2 options have to be purchased

3. The strategy is usually executed for a ‘net Credit’

4. The strategy makes limited money if the stock price goes down, and unlimited profit if

the stock price goes up. The loss is pre defined

5. There are two break even points – lower breakeven and upper breakeven points

zerodha.com/varsity

6. Spread = Higher Strike – Lower Strike

7. Net Credit = Premium Received for lower strike – 2*Premium of higher strike

8. Max Loss = Spread – Net Credit

9. Max Loss occurs at = Higher Strike

10. The payoff when market goes down = Net Credit

11. Lower Breakeven = Lower Strike + Net Credit

12. Upper Breakeven = Higher Strike + Max Loss

13. Irrespective of the time to expiry opt for slightly ITM + Slightly OTM combination of

strikes

14. Increase in volatility is good for this strategy when there is more time to expiry, but when

there is less time to expiry, increase in volatility is not really good for this strategy.

CHAPTER 5

Bear Call Ladder

5.1 – Background

The ‘Bear’ in the “Bear Call Ladder” should not deceive you to believe that this is a

bearish strategy. The Bear Call Ladder is an improvisation over the Call ratio back

spread; this clearly means you implement this strategy when you are out rightly bullish

on the stock/index.

In a Bear Call Ladder, the cost of purchasing call options is financed by selling an ‘in the

money’ call option. Further, the Bear Call Ladder is also usually setup for a ‘net credit’,

where the cash flow is invariably better than the cash flow of the call ratio back spread.

However, do note that both these strategies showcase similar payoff structures but differ

slightly in terms of the risk structure.

5.2 – Strategy Notes

The Bear Call Ladder is a 3 leg option strategy, usually setup for a “net credit”, and it

involves –

1. Selling 1 ITM call option

2. Buying 1 ATM call option

3. Buying 1 OTM call option

This is the classic Bear Call Ladder setup, executed in a 1:1:1 combination. The bear Call

Ladder has to be executed in the 1:1:1 ratio meaning for every 1 ITM Call option sold, 1

ATM and 1 OTM Call option has to be bought. Other combination like 2:2:2 or 3:3:3 (so

on and so forth) is possible.

Let’s take an example - assume Nifty Spot is at 7790 and you expect Nifty to hit 8100 by

the end of expiry. This is clearly a bullish outlook on the market. To implement the Bear

Call Ladder -

zerodha.com/varsity

1. Sell 1 ITM Call option

2. Buy 1 ATM Call option

3. Buy 1 OTM Call option

Make sure –

1. The Call options belong to the same expiry

2. Belongs to the same underlying

3. The ratio is maintained

The trade set up looks like this –

1. 7600 CE, one lot short, the premium received for this is Rs.247/-

2. 7800 CE, one lot long, the premium paid for this option is Rs.117/-

3. 7900 CE, one lot long, the premium paid for this option is Rs.70/-

4. The net credit would be 247-117-70 = 60

With these trades, the bear call ladder is executed. Let us check what would happen to

the overall cash flow of the strategies at different levels of expiry.

Do note we need to evaluate the strategy payoff at various levels of expiry as the strategy

payoff is quite versatile.

Scenario 1 – Market expires at 7600 (below the lower strike price)

We know the intrinsic value of a call option (upon expiry) is –

Max [Spot – Strike, 0]

The 7600 would have an intrinsic value of

Max [7600 – 7600, 0]

= 0

Since we have sold this option, we get to retain the premium received i.e Rs.247/-

Likewise the intrinsic value of 7800 CE and 7900 CE would also be zero; hence we lose

the premium paid i.e Rs.117 and Rs.70 respectively.

zerodha.com/varsity

Net cash flow would Premium Received – Premium paid

= 247 – 117 - 70

= 60

Scenario 2 – Market expires at 7660 (lower strike + net premium received)

The 7600 CE would have an intrinsic value of –

Max [Spot – Strike, 0]

The 7600 would have an intrinsic value of

Max [7660 – 7600, 0]

= 60

Since the 7600 CE is short, we will lose 60 from 247 and retain the balance

= 247 – 60

= 187

The 7800 and 7900 CE would expire worthless, hence we lose the premium paid i.e 117

and 70 respectively.

The total strategy payoff would be -

= 187 – 117 – 70

= 0

Hence at 7660, the strategy would neither make money nor lose money. Hence this is

considered a (lower) breakeven point.

Scenario 3 – Market expires at 7700 (between the breakeven point and

middle strike i.e 7660 and 7800)

The intrinsic value of 7600 CE would be –

zerodha.com/varsity

Max [Spot – Strike, 0]

= [7700 – 7600, 0]

= 100

Since, we have sold this option for 247 the net pay off from the option would be

247 – 100

= 147

On the other hand we have bought 7800 CE and 7900 CE, both of which would expire

worthless, hence we lose the premium paid for these options i.e 117 and 70 respectively -

Net payoff from the strategy would be –

147 – 117 – 70

= - 40

Scenario 4 – Market expires at 7800 (at the middle strike price)

Pay attention here, as this is where the tragedy strikes!

The 7600 CE would have an intrinsic value of 200, considering we have written this

option for a premium of Rs.247, we stand to lose the intrinsic value which is Rs.200.

Hence on the 7600 CE, we lose 200 and retain -

247 – 200

= 47/-

Both 7800 CE and 7900 CE would expire worthless, hence the premium that we paid

goes waste, i.e 117 and 70 respectively. Hence our total payoff would be –

47 – 117 – 70

= -140

zerodha.com/varsity

Scenario 5 – Market expires at 7900 (at the higher strike price)

Pay attention again, tragedy strikes again

The 7600 CE would have an intrinsic value of 300, considering we have written this

option for a premium of Rs.247, we stand to lose all the premium value plus more.

Hence on the 7600 CE, we lose -

247 - 300

= -53

Both 7800 CE would have an intrinsic value of 100, considering we have paid a

premium of Rs.117, the pay off for this option would be -

100 – 117

= - 17

Finally 7900 CE would expire worthless, hence the premium paid i.e 70 would go waste.

The final strategy payoff would be –

-53 – 17 – 70

= -140

Do note, the loss at both 7800 and 7900 is the same.

Scenario 6 – Market expires at 8040 (sum of long strike minus short strike

minus net premium)

Similar to the call ratio back spread, the bear call ladder has two breakeven points i.e the

upper and lower breakeven. We evaluated the lower breakeven earlier (scenario 2), and

this is the upper breakeven point. The upper breakeven is estimated as –

(7900 + 7800) – 7600 – 60

= 15700 – 7600 - 60

zerodha.com/varsity

= 8100 – 60

= 8040

Do note, both 7900 and 7800 are strikes we are long on, and 7600 is the strike we are

short on. 60 is the net credit.

So at 8040, all the call options would have an intrinsic value –

7600 CE would have an intrinsic value of 8040 – 7600 = 440, since we are short on this

at 247, we stand to lose 247 - 440 = -193.

7800 CE would have an intrinsic value of 8040 – 7800 = 240, since we are long on this

at 117, we make 240 – 117 = +123

7900 CE would have an intrinsic value of 8040 – 7900 = 140, since we are long on this

at 70, we make 140 – 70 = +70

Hence the total payoff from the Bear Call Ladder would be –

-193 + 123 + 70

= 0

Hence at 8040, the strategy would neither make money nor lose money. Hence this is

considered a (upper) breakeven point.

Do note, at 7800 and 7900 the strategy was making a loss and at 8040 the strategy

broke even. This should give you a sense that beyond 8040, the strategy would make

money. Lets just validate this with another scenario.

Scenario 7 – Market expires at 8300

At 8300 all the call options would have an intrinsic value.

7600 CE would have an intrinsic value of 8300 – 7600 = 700, since we are short on this

at 247, we stand to lose 247 - 700 = -453.

zerodha.com/varsity

7800 CE would have an intrinsic value of 8300 – 7800 = 500, since we are long on this

at 117, we make 500 – 117 = +383

7900 CE would have an intrinsic value of 8300 – 7900 = 400, since we are long on this

at 70, we make 400 - 70 = +330

Hence the total payoff from the Bear Call Ladder would be –

-453 + 383 + 330

= 260

As you can imagine, the higher the market move, the higher is the profit potential. Here

is a table that gives you the payoffs at various levels.

Do notice, when the market goes below you stand to make a modest gain of 60 points,

but when the market moves up the profits are uncapped.

5.3 – Strategy Generalization

Going by the above discussed scenarios we can make few generalizations –

 Spread = technically this is a ladder and not really a spread. However the 1

two option

legs creates a classic “spread” wherein we sell ITM and buy ATM. Hence the spread could

zerodha.com/varsity

be taken as the difference between the ITM and ITM options. In this case it would be 200

(7800 – 7600)

 Net Credit = Premium Received from ITM CE – Premium paid to ATM & OTM CE

 Max Loss = Spread (difference between the ITM and ITM options) – Net Credit

 Max Loss occurs at = ATM and OTM Strike

 The payoff when market goes down = Net Credit

 Lower Breakeven = Lower Strike + Net Credit

 Upper Breakeven = Sum of Long strike minus short strike minus net premium

Here is a graph that highlights all these important points –

Notice how the strategy makes a loss between 7660 and 8040, but ends up making a

huge profit if the market moves past 8040. Even if the market goes down you still end

up making a modest profit. But you are badly hit if the market does not move at all.

Given this characteristics of the Bear Call Ladder, I would suggest you implement the

strategy only when you are absolutely sure that the market will move, irrespective of the

direction.

From my experience, I believe this strategy is best executed on stocks (rather than

index) when the quarterly results are due.

zerodha.com/varsity

5.4 – Effect of Greeks

The effect of Greeks on this strategy is very similar to the effect of Greeks on Call Ratio

Back spread, especially the volatility bit. For your easy reference, I’m reproducing the

discussion on volatility we had in the previous chapter.

There are three colored lines depicting the change of “net premium” aka the strategy

payoff versus change in volatility. These lines help us understand the effect of increase

in volatility on the strategy keeping time to expiry in perspective.

1. Blue Line – This line suggests that an increase in volatility when there is ample time to

expiry (30 days) is beneficial for the Bear Call Ladder spread. As we can see the strategy

payoff increases from -67 to +43 when the volatility increase from 15% to 30%. Clearly

this means that when there is ample time to expiry, besides being right on the direction

of stock/index you also need to have a view on volatility. For this reason, even though

I’m bullish on the stock, I would be a bit hesitant to deploy this strategy at the start of the

zerodha.com/varsity

series if the volatility is on the higher side (say more than double of the usual volatility

reading)

2. Green line - This line suggests that an increase in volatility when there are about 15

days time to expiry is beneficial, although not as much as in the previous case. As we can

see the strategy payoff increases from -77 to -47 when the volatility increase from 15% to

30%.

3. Red line – This is an interesting, counter intuitive outcome. When there are very few

days to expiry, increase in volatility has a negative impact on the strategy! Think about it,

increase in volatility when there are few days to expiry enhances the possibility of the

option to expiry OTM, hence the premium decreases. So, if you are bullish on a stock /

index with few days to expiry, and you also expect the volatility to increase during this

period then thread cautiously.

Key takeaways from this chapter

1. Bear Call Ladder is an improvisation over the Call Ratio Spread

2. Invariably the cost of executing a bear call ladder is better than the Call Ratio Spread, but

the range above which the market has to move also becomes large

3. The Bear Call Ladder is executed by selling 1 ITM CE, buying 1 ATM CE, and 1 OTM CE

4. Net Credit = Premium Received from ITM CE – Premium paid to ATM & OTM CE

5. Max Loss = Spread (difference between the ITM and ITM options) – Net Credit

6. Max Loss occurs at = ATM and OTM Strike

7. The payoff when market goes down = Net Credit

8. Lower Breakeven = Lower Strike + Net Credit

9. Upper Breakeven = Sum of Long strike minus short strike minus net premium

10. Execute the strategy only when you are convinced that the market will move significantly

higher.

CHAPTER 6

Synthetic Long & Arbitrage

6.1 – Background

Imagine a situation where you would be required to simultaneously establish a long and

short position on Nifty Futures, expiring in the same series. How would you do this and

more importantly why would you do this?

We will address both these questions in this chapter. To begin with let us understand

how this can be done and later move ahead to understand why one would want to do

this (if you are curious, arbitrage is the obvious answer).

Options as you may have realized by now, are highly versatile derivative instruments;

you can use these instruments to create any kind of payoff structure including that of the

futures (both long and short futures payoff).

In this chapter we will understand how we can artificially replicate a long futures pay off

using options. However before we proceed, you may want to just review the long

Future’s ‘linear’ payoff here

Alternatively, here is a quick overview –

zerodha.com/varsity

As you can see, the long futures position has been initiated at 2360, and at that point

you neither make money nor lose money, hence the point at which you initiate the

position becomes the breakeven point. You make a profit as the futures move higher

than the breakeven point and you make a loss the lower the futures move below the

breakeven point. The amount of profit you make for a 10 point up move is exactly the

same as the amount of loss you’d make for a 10 point down move. Because of this

linearity in payoff, the future is also called a linear instrument.

The idea with a Synthetic Long is to build a similar long Future’s payoff using options.

6.2 – Strategy Notes

Executing a Synthetic Long is fairly simple; all that one has to do is –

1. Buy the ATM Call Option

2. Sell the ATM Put Option

When you do this, you need to make sure –

1. The options belong to the same underlying

2. Belongs to the same expiry

zerodha.com/varsity

Let us take an example to understand this better. Assume Nifty is at 7389, which would

make 7400 the ATM strike. Synthetic Long would require us to go long on 7400 CE, the

premium for this is Rs.107 and we would short the 7400 PE at 80.

The net cash outflow would be the difference between the two premiums i.e 107 – 80

= 27.

Let us consider a few market expiry scenarios –

Scenario 1 – Market expires at 7200 (below ATM)

At 7200, the 7400 CE would expire worthless, hence we would lose the premium paid i.e

Rs.107/-. However the 7400 PE would have an intrinsic value, which can be calculated

as follows –

Intrinsic value of Put Option = Max [Strike-Spot, 0]

= Max [7400 – 7200, 0]

=Max [200, 0]

= 200.

Clearly, since we are short on this option, we would lose money from the premium we

have received. The loss would be –

80 – 200 = -120

Total payoff from the long Call and short Put position would be –

= -107 – 120

= -227

Scenario 2 – Market expires at 7400 (At ATM)

If the market expires exactly at 7400, both the options would expire worthless and

hence –

zerodha.com/varsity

1. We lose the premium paid for the 7400 CE option i.e 107

2. We get the retain the premium for the 7400 PE option i.e 80

3. Net payoff from both the positions would be -27e 80 – 107

Do note, 27 also happens to be the net cash outflow of the strategy, which is also the

difference between the two premiums

Scenario 3 – Market expires at 7427 (ATM + Difference between the two

premiums)

7427 is an interesting level, this is the breakeven point for the strategy, where we neither

make money nor lose money.

1. 7400 CE – the option is ITM and has an intrinsic value of 27. However we have paid 107

as premium hence we experience a total loss of 80

2. 7400 PE – the option would expire OTM, hence we get to retain the entire premium of

80.

3. On one hand we make 80 and the other we lose 80. Hence we neither make nor lose any

money, making 7427 the breakeven point for this strategy.

Scenario 4 – Market expires at 7600 (above ATM)

At 7600, the 7400 CE would have an intrinsic value of 200, we would make -

Intrinsic value – Premium

= 200 – 107

= 93

The 7400 PE would expire worthless; hence we get to retain the entire premium of

Rs.80.

Total payoff from the strategy would be –

= 93 + 80

= 173

zerodha.com/varsity

With the above 4 scenarios, we can conclude that the strategy makes money while the

market moves higher and loses money while the market goes lower, similar to futures.

However this still does not necessarily mean that the payoff is similar to that of futures.

To establish that the synthetic long payoff behaves similar to futures, we need evaluate

the payoff of the strategy with reference to the breakeven point; let’s say 200 point

above and below the breakeven point. If the payoff is identical, then clearly there is

linearity in the payoff, similar to futures.

So let’s figure this out.

We know the breakeven point for this is –

ATM + difference between the premiums

= 7400 + 27

= 7427

The payoff around this point should be symmetric. We will consider 7427 + 200 =

7627 and 7427-200 = 7227 for this.

At 7627 –

1. The 7400 CE would have an intrinsic value of 227, hence we get to make 227 – 107 = 120

2. The 7400 PE would expire worthless, hence we get to keep the entire premium of 80

3. In all we experience a payoff of 120 + 80 = 200

At 7227 –

1. The 7400 CE would not have any intrinsic value, hence we lose the entire premium paid

i.e 107

2. The 7400 PE would have an intrinsic value of 7400 – 7227 = 173, since we have received

80 as premium the net loss would be 80 – 173 = -93.

3. In all we experience a payoff of -93-107 = -200

Clearly, there is payoff symmetry around the breakeven, and for this reason,

the Synthetic Long mimics the payoff of the long futures instrument.

zerodha.com/varsity

Further, here is the payoff at various expiry levels –

And when you plot the Net Payoff, we get the payoff structure which is similar to the

long call futures.

zerodha.com/varsity

Having figured out how to set up a Synthetic long, we need to figure out the typical

circumstances under which setting up a synthetic long is required.

6.3 – The Fish market Arbitrage

I’ll assume that you have a basic understanding on Arbitrage. In easy words, arbitrage is

an opportunity to buy goods/asset in a cheaper market and sell the same in expensive

markets and pocket the difference in prices. If executed well, arbitrage trades are almost

risk free. Let me attempt to give you a simple example of an arbitrage opportunity.

Assume you live by a coastal city with abundant supply of fresh sea fish, hence the rate

at which fish is sold in your city is very low, let’s say Rs.100 per Kg. The neighboring city

which is 125 kms away has a huge demand for the same fresh sea fish. However, in this

neighboring city the same fish is sold at Rs.150 per Kg.

Given this if you can manage to buy the fish from your city at Rs.100 and manage to sell

the same in the neighboring city at Rs.150, then in process you clearly get to pocket the

price differential i.e Rs.50. Maybe you will have to account for transportation and other

logistics, and instead of Rs.50, you get to keep Rs.30/- per Kg. This is still a beautiful

deal and this is a typical arbitrage in the fish market!

zerodha.com/varsity

It looks perfect, think about it - if you can do this everyday i.e buy fish from your city at

Rs.100 and sell in the neighboring city at Rs.150, adjust Rs.20 towards expenses then

Rs.30 per KG is guaranteed risk free profit.

This is indeed risk free, provides nothing changes. But if things change, so will your

profitability, let me list few things that could change -

1. No Fish (opportunity risk) – Assume one day you go to the market to buy fish at

Rs.100, and you realize there is no fish in the market. Then you have no opportunity to

make Rs.30/-.

2. No Buyers (liquidity risk) – You buy the fish at Rs.100 and go to the neighboring

town to sell the same at Rs.150, but you realize that there are no buyers. You are left

holding a bag full of dead fish, literally worthless!

3. Bad bargaining (execution risk) – The entire arbitrage opportunity hinges upon the

fact that you can ‘always’ bargain to buy at Rs.100 and sell at Rs.150. What if on a bad

day you happen to buy at 110 and sell at 140? You still have to pay 20 for transport, this

means instead of the regular 30 Rupees profit you get to make only 10 Rupees, and if this

continues, then the arbitrage opportunity would become less attractive and you may not

want to do this at all.

zerodha.com/varsity

4. Transport becomes expensive (cost of transaction) – This is another crucial

factor for the profitability of the arbitrage trade. Imagine if the cost of transportation

increases from Rs.20 to Rs.30? Clearly the arbitrage opportunity starts looking less

attractive as the cost of execution goes higher and higher. Cost of transaction is a critical

factor that makes or breaks an arbitrage opportunity

5. Competition kicks in (who can drop lower?) – Given that the world is inherently

competitive you are likely to attract some competition who would also like to make that

risk free Rs.30. Now imagine this –

a. So far you are the only one doing this trade i.e buy fish at Rs.100 and sell at

Rs.150

b. Your friend notices you are making a risk free profit, and he now wants to copy

you. You can’t really prevent his as this is a free market.

c. Both of you buy at Rs.100, transport it at Rs.20, and attempt to sell it in the

neighboring town

d. A potential buyer walks in, sees there is a new seller, selling the same quality of

fish. Who between the two of you is likely to sell the fish to the buyer?

e. Clearly given the fish is of the same quality the buyer will buy it from the one

selling the fish at a cheaper rate. Assume you want to acquire the client, and

therefore drop the price to Rs.145/-

f. Next day your friend also drops the price, and offers to sell fish at Rs.140 per KG,

and therefore igniting a price war. In the whole process the price keeps dropping

and the arbitrage opportunity just evaporates.

g. How low can the price drop? Obviously it can drop to Rs.120 (cost of buying fish

plus transport). Beyond 120, it does not makes sense to run the business

h. Eventually in a perfectly competitive world, competition kicks in and arbitrage

opportunity just ceases to exist. In this case, the cost of fish in neighboring town

would drop to Rs.120 or a price point in that vicinity.

I hope the above discussion gave you a quick overview on arbitrage. In fact we can

define any arbitrage opportunity in terms of a simple mathematical expression, for

example with respect to the fish example, here is the mathematical equation –

[Cost of selling fish in town B - Cost of buying fish in town A] = 20

If there is an imbalance in the above equation, then we essentially have an arbitrage

opportunity. In all types of markets - fish market, agri market, currency market, and

zerodha.com/varsity

stock market such arbitrage opportunities exist and they are all governed by simple

arithmetic equations.

6.4 – The Options arbitrage

Arbitrage opportunities exist in almost every market, one needs to be a keen observer of

the market to spot it and profit from it. Typically stock market based arbitrage

opportunities allow you to lock in a certain profit (small but guaranteed) and carry this

profit irrespective of which direction the market moves. For this reason arbitrage trades

are quite a favorite with risk intolerant traders.

I would like to discuss a simple arbitrage case here, the roots of which lie in the concept

of ‘Put Call Parity’. I will skip discussing the Put Call Parity theory but would instead

jump to illustrate one of its applications.

However I’d suggest you watch this beautiful video from Khan Academy to understand

the Put Call Parity –

So based on Put Call Parity, here is an arbitrage equation –

Long Synthetic long + Short Futures = 0

You can elaborate this to –

Long ATM Call + Short ATM Put + Short Futures = 0

The equation states that the P&L upon expiry by virtue of holding a long synthetic long

and short future should be zero. Why should this position result in a zero P&L, well the

answer to this is attributable to the Put Call Parity.

However, if the P&L is a non zero value, then we have an arbitrage opportunity.

Here is an example that will help you understand this well.

zerodha.com/varsity

On 21

Jan, Nifty spot was at 7304, and the Nifty Futures was trading at 7316.

zerodha.com/varsity

The 7300 CE and PE (ATM options) were trading at 79.5 and 73.85 respectively. Do

note, all the contracts belong to the January 2016 series.

Going by the arbitrage equation stated above, if one were to execute the trade, the

positions would be –

1. Long 7300 CE @ 79.5

2. Short 7300 PE @ 73.85

3. Short Nifty futures @ 7316

Do note, the first two positions together form a long synthetic long. Now as per the

arbitrage equation, upon expiry the positions should result in a zero P&L. Let’s evaluate

if this holds true.

Scenario 1 – Expiry at 7200

 The 7300 CE would expire worthless, hence we lose the premium paid i.e 79.5

 The 7300 PE would have an intrinsic value of 100, but since we are short at 73.85, the

net payoff would be 73.85 – 100 = -26.15

zerodha.com/varsity

 We are short on futures at 7316, which would result in a profit of 116 points (7316 –

7200)

 Net payoff would be -79.5 – 26.15 + 116 = +10.35

Clearly, instead of a 0 payoff, we are experiencing a positive non zero P&L.

Scenario 2 – Expiry at 7300

 The 7300 CE would expire worthless, hence we lose the premium paid i.e 79.5

 The 7300 PE would expire worthless, hence we get to retain 73.85

 We are short on futures at 7316, which would result in a profit of 16 points (7316 – 7300)

 Net payoff would be -79.5 +73.85+16 = +10.35

Scenario 3 – Expiry at 7400

 The 7300 CE would have an intrinsic value of 100, and therefore the payoff would be 100

– 79.5 = 20.5

 The 7300 PE would expire worthless, hence we get to retain 73.85

 We are short on futures at 7316, which would result in loss of 84 points (7316 – 7400)

 Net payoff would be 20.5 + 73.85 - 84 = +10.35

You could test this across any expiry value (in other words the markets can move in any

direction) but you are likely to pocket 10.35 points, upon expiry. I’d like to stress this

again; this arbitrage lets you make 10.35, upon expiry.

Here is the payoff structure at different expiry values –

zerodha.com/varsity

Interesting isn’t it? But what’s the catch you may ask?

Transaction charges!

One has to account for the cost of execution of this trade and figure out if it still makes

sense to take up the trade. Consider this –

 Brokerage – if you are trading with a traditional broker, then you will be charged on a

percentage basis which will eat away your profits. So on one hand you make 10 points,

but you may end up paying 8 – 10 points as brokerage. However if you were to do this

trade with a discount broker like Zerodha, your breakeven on this trade would be around

4-5 points. This should give you more reason to open your account with Zerodha

 STT – Do remember the P&L is realised upon expiry; hence you would have to carry

forward your positions to expiry. If you are long on an ITM option (which you will be)

then upon expiry you will have to pay a hefty STT, which will further eat away your

profits. Please do read this to know more.

 Other applicable taxes – Besides you also have to account for service tax, stamp duty

etc

So considering these costs, the efforts to carry an arbitrage trade for 10 points may not

make sense. But it certainly would, if the payoff was something better, maybe like 15 or

zerodha.com/varsity

20 points. With 15 or 20 points you can even maneuver the STT trap by squaring off the

positions just before expiry - although it will shave off a few points.

Key takeaways from this chapter

1. You can use options to replicate futures payoff

2. A synthetic long replicates the long futures payoff

3. Simultaneously buying ATM call and selling ATM Put creates a synthetic long

4. The breakeven point for the synthetic long is the ATM strike + net premium paid

5. An arbitrage opportunity is created when Synthetic long + short futures yields a positive

non zero P&L upon expiry

6. Execute the arbitrage trade only if the P&L upon expiry makes sense after accounting for

expenses.

CHAPTER 7

Bear Put Spread

7.1 – Spreads versus naked positions

Over the last five chapters we’ve discussed various multi leg bullish strategies. These

strategies ranged to suit an assortment of market outlook - from an outrightly bullish

market outlook to moderately bullish market outlook. Reading through the last 5

chapters you must have realised that most professional options traders prefer initiating

a spread strategy versus taking on naked option positions. No doubt, spreads tend to

shrink the overall profitability, but at the same time spreads give you a greater visibility

on risk. Professional traders value ‘risk visibility’ more than the profits. In simple words,

it’s a much better deal to take on smaller profits as long as you know what would be your

maximum loss under worst case scenarios.

Another interesting aspect of spreads is that invariably there is some sort of financing

involved, wherein the purchase of an option is funded by the sale of another option. In

fact, financing is one of the key aspects that differentiate a spread versus a normal naked

directional position. Over the next few chapters we will discuss strategies which you can

deploy when your outlook ranges from moderately bearish to out rightly bearish. The

composition of these strategies is similar to the bullish strategies that we discussed

earlier in the module.

The first bearish strategy we will look into is the Bear Put Spread, which as you may

have guessed is the equivalent of the Bull Call Spread.

zerodha.com/varsity

7.2 – Strategy notes

Similar to the Bull Call Spread, the Bear Put Spread is quite easy to implement. One

would implement a bear put spread when the market outlook is moderately bearish, i.e

you expect the market to go down in the near term while at the same time you don’t

expect it to go down much. If I were to quantify ‘moderately bearish’, a 4-5% correction

would be apt. By invoking a bear put spread one would make a modest gain if the

markets correct (go down) as expected but on the other hand if the markets were to go

up, the trader will end up with a limited loss.

A conservative trader (read as risk averse trader) would implement Bear Put Spread

strategy by simultaneously –

1. Buying an In the money Put option

2. Selling an Out of the Money Put option

There is no compulsion that the Bear Put Spread has to be created with an ITM and

OTM option. The Bear Put spread can be created employing any two put options. The

choice of strike depends on the aggressiveness of the trade. However do note that both

the options should belong to the same expiry and same underlying. To understand the

zerodha.com/varsity

implementation better, let’s take up an example and see how the strategy behaves under

different scenarios.

As of today Nifty is at 7485, this would make 7600 PE In the money and 7400 PE Out of

the money. The ‘Bear Put Spread’ would require one to sell 7400 PE, the premium

received from the sale would partially finance the purchase of the 7600 PE. The

premium paid (PP) for the 7600 PE is Rs.165, and the premium received (PR) for the

7400 PE is Rs.73/-. The net debit for this transaction would be –

73 – 165

= -92

To understand how the payoff of the strategy works under different expiry

circumstances, we need to consider different scenarios. Please do bear in mind the

payoff is upon expiry, which means to say that the trader is expected to hold these

positions till expiry.

Scenario 1 – Market expires at 7800 (above long put option i.e 7600)

This is a case where the market has gone up as opposed to the expectation that it would

go down. At 7800 both the put option i.e 7600 and 7400 would not have any intrinsic

value, hence they would expire worthless.

 The premium paid for 7600 PE i.e Rs.165 would go to 0, hence we retain nothing

 The premium received for 7400 PE i.e Rs.73 would be retained entirely

 Hence at 7800, we would lose Rs.165 on one hand but this would be partially

offset by the premium received i.e Rs.73

 The overall loss would be -165 + 73 = -92

Do note the ‘-ve’ sign associated with 165 indicates that this is a money outflow from the

account, and the ‘+ve’ sign associated with 73 indicates that the money is received into

the account.

Also, the net loss of 92 is equivalent to the net debit of the strategy.

Scenario 2 – Market expired at 7600 (at long put option)

zerodha.com/varsity

In this scenario we assume the market expires at 7600, where we have purchased a Put

option. But then, at 7600 both 7600 and 7400 PE would expire worthless (similar to

scenario 1) resulting in a loss of -92.

Scenario 3 – Market expires at 7508 (breakeven)

7508 is half way through 7600 and 7400, and as you may have guessed I’ve picked 7508

specifically to showcase that the strategy neither makes money nor loses any money at

this specific point.

 The 7600 PE would have an intrinsic value equivalent to Max [7600 -7508, 0],

which is 92.

 Since we have paid Rs.165 as premium for the 7600 PE, some of the premium

paid would be recovered. That would be 165 – 92 = 73, which means to say the

net loss on 7600 PE at this stage would be Rs.73 and not Rs.165

 The 7400 PE would expire worthless, hence we get to retain the entire premium

of Rs.73

 So on hand we make 73 (7400 PE) and on the other we lose 73 (7600 PE)

resulting in a no loss no profit situation

Hence, 7508 would be the breakeven point for this strategy.

Scenario 4 – Market expires at 7400 (at short put option)

This is an interesting level, do recall when we initiated the position the spot was at 7485,

and now the market has gone down as expected. At this point both the options would

have interesting outcomes.

 The 7600 PE would have an intrinsic value equivalent to Max [7600 -7400, 0],

which is 200

 We have paid a premium of Rs.165, which would be recovered from the intrinsic

value of Rs.200, hence after compensating for the premium paid one would

retain Rs.35/-

 The 7400 PE would expire worthless, hence the entire premium of Rs.73 would

be retained

 The net profit at this level would be 35+73 = 108

zerodha.com/varsity

The net payoff from the strategy is in line with the overall expectation from the strategy

i.e the trader gets to make a modest profit when the market goes down.

Scenario 5 – Market expires at 7200 (below the short put option)

This is again an interesting level as both the options would have an intrinsic value. Lets

figure out how the numbers add up –

 The 7600 PE would have an intrinsic value equivalent to Max [7600 -7200, 0],

which is 400

 We have paid a premium of Rs.165, which would be recovered from the intrinsic

value of Rs.400, hence after compensating for the premium paid one would

retain Rs.235/-

 The 7400 PE would have an intrinsic value equivalent to Max [7400 -7200, 0],

which is 200

 We received a premium of Rs.73, however we will have to let go of the premium

and bear a loss over and above 73. This would be 200 -73 = 127

 On one hand we make a profit of Rs.235 and on the other we lose 127, therefore

the net payoff of the strategy would be 235 – 127 = 108.

Summarizing all the scenarios (I’ve put up the payoff values directly after considering

the premiums)

Do note, the net payoff from the strategy is in line with the overall expectation from the

strategy i.e the trader gets to make a modest profit when the market goes down while at

the same time the losses are capped in case the market goes up.

Have a look at the table below -

zerodha.com/varsity

The table below shows the strategy payoff at different expiry levels. The losses are

capped to 92 (when markets go up) and the profits are capped to 108 (when markets go

down).

7.3 – Strategy critical levels

From the above discussed scenarios we can generalize a few things –

1. Strategy makes a loss if the spot moves above the breakeven point, and makes a

profit below the breakeven point

2. Both the profits and loss are capped

3. Spread is difference between the two strike prices.

a. In this example spread would be 7600 – 7400 = 200

4. Net Debit = Premium Paid – Premium Received

a. 165 – 73 = 92

5. Breakeven = Higher strike – Net Debit

a. 7600 – 92 = 7508

6. Max profit = Spread – Net Debit

a. 200 – 92 = 108

7. Max Loss = Net Debit

a. 92

zerodha.com/varsity

You can note all these critical points in the strategy payoff diagram -

7.4 – Quick note on Delta

This is something I missed talking about in the earlier chapters, but its better late than

never :-). Whenever you implement an options strategy always add up the deltas. I used

the B&S calculator to calculate the deltas.

The delta of 7600 PE is -0.618

The delta of 7400 PE is – 0.342

zerodha.com/varsity

The negative sign indicates that the put option premium will go down if the markets go

up, and premium gains value if the markets go down. But do note, we have written the

7400 PE, hence the Delta would be

-(-0.342)

+ 0.342

Now, since deltas are additive in nature we can add up the deltas to give the combined

delta of the position. In this case it would be –

-0.618 + (+0.342)

= - 0.276

This means the strategy has an overall delta of 0.276 and the ‘–ve’ indicates that the

premiums will go up if the markets go down. Similarly you can add up the deltas of

other strategies we’ve discussed earlier - Bull Call Spread, Call Ratio Back spread etc and

you will realize they all have a positive delta indicating that the strategy is bullish.

When you have more than 2 option legs it gets really difficult to estimate the overall bias

of the strategy (whether the strategy is bullish or bearish), in such cases you can quickly

add up the deltas to know the bias. Further, if in case the deltas add to zero, then it

zerodha.com/varsity

means that the strategy is not really biased to any direction. Such strategies are called

‘Delta Neutral’. We will eventually discuss these strategies at a later point in this

module.

Also, you may be interested to know that while the delta neutral strategies are immune

to market’s directional move, they react to changes in volatility and time, hence these

are also sometime called “Volatility based strategies”.

7.5 – Strike selection and effect of volatility

The strike selection for a bear put spread is very similar to the strike selection

methodology of a bull call spread. I hope you are familiar with the ‘1

half of the series’

and ‘2

half of the series’ methodology. If not I’d suggest you to kindly read

through section 2.3.

Have a look at the graph below –

If we are in the first half of the series (ample time to expiry) and we expect the market to

go down by about 4% from present levels, choose the following strikes to create the

spread

zerodha.com/varsity

We will now shift our focus on the effect of volatility on the bear put spread. Have a look

at the following image –

The graph above explains how the premium varies with respect to variation in volatility

and time.

 The blue line suggests that the cost of the strategy does not vary much with the

increase in volatility when there is ample time to expiry (30 days)

 The green line suggests that the cost of the strategy varies moderately with the

increase in volatility when there is about 15 days to expiry

 The red line suggests that the cost of the strategy varies significantly with the

increase in volatility when there is about 5 days to expiry

From these graphs it is clear that one should not really be worried about the changes in

the volatility when there is ample time to expiry. However one should have a view on

volatility between midway and expiry of the series. It is advisable to take the bear put

spread only when the volatility is expected to increase, alternatively if you expect the

volatility to decrease, its best to avoid the strategy.

Key takeaways from this chapter

1. Spread offers visibility on risk but at the same time shrinks the reward

2. When you create a spread, the proceeds from the sale of an option offsets the

purchase of an option

3. Bear put spread is best invoked when you are moderately bearish on the markets

4. Both the profits and losses are capped

5. Classic bear put spread involves simultaneously purchasing ITM put options and

selling OTM put options

6. Bear put spread usually results in a net debit

7. Net Debit = Premium Paid – Premium Received

8. Breakeven = Higher strike – Net Debit

9. Max profit = Spread – Net Debit

10. Max Loss = Net Debit

11. Select strikes based on the time to expiry

12. Implement the strategy only when you expect the volatility to increase (especially

in the 2

half of the series)

CHAPTER 8

Bear Call Spread

8.1 – Choosing Calls over Puts

Similar to the Bear Put Spread, the Bear Call Spread is a two leg option strategy invoked

when the view on the market is ‘moderately bearish’. The Bear Call Spread is similar to

the Bear Put Spread in terms of the payoff structure; however there are a few differences

in terms of strategy execution and strike selection. The Bear Call spread involves

creating a spread by employing ‘Call options’ rather than ‘Put options’ (as is the case in

bear put spread).

You may have a fundamental question at this stage – when the payoffs from both Bear

Put spread and Bear Call spread are similar, why should one choose a Bear Call spread

over a Bear Put spread?

zerodha.com/varsity

Well, this really depends on how attractive the premiums are. While the Bear Put spread

is executed for a debit, the Bear Call spread is executed for a credit. So if you are at a

point in the market where –

1. The markets have rallied considerably (therefore CALL premiums have swelled)

2. The volatility is favorable

3. Ample time to expiry

And you have a moderately bearish outlook going forward, then it makes sense to invoke

a Bear Call Spread for a net credit as opposed to invoking a Bear Put Spread for a net

debit. Personally I do prefer strategies which offer net credit rather than strategies

which offer net debit.

8.2 – Strategy Notes

The Bear Call Spread is a two leg spread strategy traditionally involving ITM and OTM

Call options. However you can create the spread using other strikes as well. Do

remember, the higher the difference between the two selected strikes (spread), larger is

the profit potential.

To implement the bear call spread –

1. Buy 1 OTM Call option (leg 1)

2. Sell 1 ITM Call option (leg 2)

Ensure –

1. All strikes belong to the same underlying

2. Belong to the same expiry series

3. Each leg involves the same number of options

Let us take up example to understand this better -

Date – February 2016

Outlook – Moderately bearish

Nifty Spot – 7222

zerodha.com/varsity

Bear Call Spread, trade set up -

1. Buy 7400 CE by paying Rs.38/- as premium; do note this is an OTM option.

Since money is going out of my account this is a debit transaction

2. Sell 7100 CE and receive Rs.136/- as premium, do note this is an ITM option.

Since I receive money, this is a credit transaction

3. The net cash flow is the difference between the debit and credit i.e 136 – 38

= +98, since this is a positive cashflow, there is a net credit to my account.

Generally speaking in a bear call spread there is always a ‘net credit’, hence the bear call

spread is also called referred to as a ‘credit spread’. After we initiate the trade, the

market can move in any direction and expiry at any level. Therefore let us take up a few

scenarios to get a sense of what would happen to the bear put spread for different levels

of expiry.

Scenario 1 – Market expires at 7500 (above the long Call)

At 7500, both the Call options would have an intrinsic value and hence they both would

expire in the money.

 7400 CE would have an intrinsic value of 100, since we have paid a premium of

Rs.38, we would be in a profit of 100 – 38 = 62

 7100 CE would have an intrinsic value of 400, since we have sold this option at

Ra.136, we would incur a loss of 400 – 136 = -264

 Net loss would be -264 + 62 = - 202

Scenario 2 – Market expires at 7400 (at the long call)

At 7400, the 7100 CE would have an intrinsic value and hence would expire in the

money. The 7400 CE would expire worthless.

 7400 CE would expire worthless, hence the entire premium of Rs.38 would be

written of as a loss.

 7100 CE would have an intrinsic value of 300, since we have sold this option at

Ra.136, we would incur a loss of 300 – 136 = -164

 Net loss would be -164 -38 = - 202

zerodha.com/varsity

Do note, the loss at 7400 is similar to the loss at 7500 pointing to the fact that above a

certain point loss is capped to 202.

Scenario 3 – Market expires at 7198 (breakeven)

At 7198, the trade neither makes money or losses money, hence this is considered a

breakeven point. Let us see how the numbers play out here –

 At 7198, the 7100CE would expire with an intrinsic value of 98. Since we have

sold the option at Rs.136, we get to retain a portion of the premium i.e 136 – 98

= +38

 7400 CE would expire worthless, hence we will lose the premium paid i.e 38

 Net payoff would -38 + 38 = 0

This clearly indicates that the strategy neither makes money or losses money at 7198.

Scenario 4 – Market expires at 7100 (at the short call)

At 7100, both the Call options would expire worthless, hence it would be out of the

money.

 7400 would not have any value, hence the premium paid would be a complete

loss, i.e Rs.38

 7100 will also not have any intrinsic value, hence the entire premium received i.e

Rs.136 would be retained back

 Net profit would be 136 - 38 = 98

Clearly, as and when the market falls, the strategy makes a profit.

Scenario 5 – Market expires at 7000 (below the short call)

This scenario tests the profitability of the strategy when the market falls further. At

7000, both the call options would expire worthless. While we treat the premium paid for

7400 CE i.e Rs.38 as a loss , we will retain the entire premium received for 7100 CE i.e

Rs.136 as a profit. Hence the net profit from the strategy would be 136-38 = 98. Clearly,

as and when the market falls, the strategy tends to make money, but it is capped to

Rs.98.

zerodha.com/varsity

Here is the payoff for the strategy at different expiries –

These payoffs can be plotted to get the graph of the strategy payoff –

As you can observe, the payoff is similar to a bear put spread where both the profits

under best case scenario and losses under worst case scenario is pre defined.

8.3 – Strategy Generalization

zerodha.com/varsity

Going by the above payoff we can generalize the key trigger points for the strategy –

 Spread = Difference between the strikes

o 7400 – 7100 = 300

 Net Credit = Premium Received – Premium Paid

o 136 – 38 = 98

 Breakeven = Lower strike + Net Credit

o 7100 + 98 = 7198

 Max Profit = Net Credit

 Max Loss = Spread – Net Credit

o 300 – 98 = 202

At this stage, we can add up the Deltas to get the overall position delta to know the

strategy’s sensitivity to the directional movement.

From the BS calculator I got the Delta values as follows –

 7400 CE is OTM option and has a delta of +0.32

 7100 CE is ITM option and has a delta of +0.89

 Since we are short 7100 CE, the delta is –(+0.89) = -0.89

 Overall position delta is = +0.32 + (-0.89) = -0.57

The delta of the strategy is negative, and it indicates that the strategy makes money

when the underlying goes down, and makes a loss when the underlying goes up.

8.4 – Strike Selection and impact of Volatility

The following images help us identify the best call option strikes to choose, given the

time to expiry. We have discussed the split up of time frame (1

and 2

half of the

series) several times before, hence for this reason I will just post the graphs and the

summary table.

The following graph talks about the variation in strategy cost with respect to changes in

The graph above explains how the premium varies with respect to variation in volatility

and time.

 The blue line suggests that the cost of the strategy does not vary much with the

increase in volatility when there is ample time to expiry (30 days)

 The green line suggests that the cost of the strategy varies moderately with the

increase in volatility when there is about 15 days to expiry

 The red line suggests that the cost of the strategy varies significantly with the

increase in volatility when there is about 5 days to expiry

From these graphs it is clear that one should not really be worried about the changes in

the volatility when there is ample time to expiry. However one should have a view on

volatility between midway and expiry of the series. It is advisable to take the bear call

spread only when the volatility is expected to increase, alternatively if you expect the

volatility to decrease, its best to avoid the strategy.

CHAPTER 9

Put Ratio Back Spread

9.1 – Background

We discussed the “Call Ratio Back spread” strategy extensively in chapter 4 of this

module. The Put ratio back spread is similar except that the trader invokes this when he

is bearish on the market or stock.

At a broad level this is what you will experience when you implement the Put Ratio Back

Spread

1. Unlimited profit if the market goes down

2. Limited profit if market goes up

3. A predefined loss if the market stays within a range

In simpler words you make money as long as the market moves in either direction, of

course the strategy is more favorable if market goes down.

zerodha.com/varsity

Usually, the Put Ratio Back Spread is deployed for a ‘net credit’, meaning money flows

into your account as soon as you execute Put Ratio Back Spread. The ‘net credit’ is what

you make if the market goes up, as opposed to your expectation (i.e market going down).

On the other hand if the market indeed goes down, then you stand to make an unlimited

profit.

I suppose this should also explain why the put ratio back spread is better than buying a

plain vanilla put option.

9.2 – Strategy Notes

The Put Ratio Back Spread is a 3 leg option strategy as it involves buying two

OTM Put options and selling one ITM Put option. This is the classic 2:1 combo. In

fact the put ratio back spread has to be executed in the 2:1 ratio meaning 2 options

bought for every one option sold, or 3 options bought for every 2 options sold, so on and

so forth.

zerodha.com/varsity

Let take an example - Nifty Spot is at 7506 and you expect Nifty to hit 7000 by the end

of expiry. This is clearly a bearish expectation. To implement the Put Ratio Back Spread

1. Sell one lot of 7500 PE (ITM)

2. Buy two lots of 7200 PE (OTM)

Make sure –

1. The Put options belong to the same expiry

2. Belong to the same underlying

3. The ratio is maintained

The trade set up looks like this –

1. 7500 PE, one lot short, the premium received for this is Rs.134/-

2. 7200 PE, two lots long, the premium paid is Rs.46/- per lot, so Rs.92/- for 2 lots

3. Net Cash flow is = Premium Received – Premium Paid i.e 134 – 92 = 42 (Net

Credit)

With these trades, the Put ratio back spread is executed. Let us check what would

happen to the overall cash flow of the strategies at different levels of expiry.

Do note we need to evaluate the strategy payoff at various levels of expiry, as the

strategy payoff is quite versatile.

Scenario 1 – Market expires at 7600 (above the ITM option)

At 7600, both the Put options would expire worthless. The intrinsic value of options and

the eventual strategy payoff is as below –

 7200 PE, would expire worthless, since we are long 2 lots of this option at Rs.46

per lot, we would lose the entire premium of Rs.92 paid

 7500 PE would also expire worthless, but we have written this option and

received a premium of Rs.134, which in this case can be retained back

 The net payoff from the strategy is 134 – 92 = 42

zerodha.com/varsity

Do note, the net payoff of the strategy at 7600 (higher than the ITM strike) is equivalent

to the net credit.

Scenario 2 – Market expires at 7500 (at the higher strike i.e the ITM option)

At 7500 both the options would have no intrinsic value, hence they both would expire

worthless. Hence the payoff would be similar to the payoff we discussed at 7600. Hence

the net strategy payoff would be equal to Rs.42 (net credit).

In fact as you may have guessed, the payoff of the strategy at any point above 7500 is

equal to the net credit.

Scenario 3 – Market expires at 7458 (higher break even)

Like in the call ratio back spread strategy, the put ratio back spread too has two

breakeven points i.e the upper breakeven and the lower breakeven point. 7458 marks

the upper breakeven level; of course we will discuss how we arrived at the upper

breakeven point a little later in the chapter.

 At 7458, the 7500 PE will have an intrinsic value. As you may recall, the put

option intrinsic value can be calculated as Max[Strike – Spot, 0] i.e Max[7500 –

7458, 0] hence 42

 Since we have sold 7500 PE at 134, we will lose a portion of the premium received

and retain the rest. Hence the payoff would be 134 – 42 = 92

 The 7200 PE will not have any intrinsic value, hence the entire premium paid i.e

92 is lost

 So on one hand we made 92 on the 7500 PE and on the other we would lose 92

on the 7200 PE resulting in no loss, no gain. Thus, 7458 marks as one of the

breakeven points.

Scenario 4 – Market expires at 7200 (Point of maximum pain)

This is the point at which the strategy causes maximum pain, let us figure out why.

 At 7200, 7500 PE would have an intrinsic value of 300 (7500 – 7200). Since we

have sold this option and received a premium of Rs.134, we would lose the entire

premium received and more. The payoff on this would be 134 - 300 = - 166

zerodha.com/varsity

 7200 PE would expire worthless as it has no intrinsic value. Hence the entire

premium paid of Rs.92 would be lost

 The net strategy payoff would be -166 – 92 = - 258

 This is a point where both the options would turn against us, hence is considered

as the point of maximum pain

Scenario 5 – Market expires at 6942 (lower break even)

At 6942, both the options would have an intrinsic value; however this is the lower

breakeven point. Let’s figure out how this works –

 At 6942, 7500 PE will have an intrinsic value equivalent of 7500 – 6942 = 558.

Since have sold this option at 134, the payoff would be 134 – 558 = - 424

 The 7200 PE will also have an intrinsic value equivalent of 7200 – 6942 = 258

per lot, since we are long two lots the intrinsic value adds upto 516. We have

initially paid a premium of Rs.92 (both lots included), hence this needs to be

deducted to arrive at the payoff would be 516 – 92 = +424

 So on one hand we make 424 on the 7200 PE and on the other we would lose 424

on the 7500 PE resulting in no loss, no gain. Thus, 6942 marks as one of the

breakeven points.

Scenario 6 – Market expires at 6800 (below the lower strike price)

Remember, the put ratio backspread is a bearish strategy. It is supposed to make money

once the market goes below the lower breakeven point. So lets understand how the pay

off behaves at a point lower than the lower breakeven point.

 At 6800, 7500 PE will have an intrinsic value of 700 and since we are short

7500PE at 134, we would lose 134 -700 = - 566

 7200 PE will have an intrinsic value of 400. Since we are long 2 lots, the intrinsic

value would be 800. Premium paid for two lots is Rs.92, hence after adjusting for

the premium paid, we get to make 800 – 92 = +708

 Net strategy payoff would be 708 – 566 = +142

zerodha.com/varsity

Likewise, you can evaluate the strategy payoff at different levels of market expiry and

you will realize that the profits are uncapped as long as the market continues to slide.

The following table showcases the same –

Plotting the different payoff points, gives us the strategy payoff graph –

Clearly from the graph above, we can conclude –

1. If markets go down, then the profits are unlimited

zerodha.com/varsity

2. There are two breakeven points

3. The point at which maximum loss occurs is at 7200

4. If markets goes up, then the profits are limited

9.3 – Strategy generalization

We can generalize the key strategy levels as below –

1. Spread = Higher Strike – lower strike

a. 7500 – 7200 = 300

2. Max loss = Spread – Net credit

a. 300 – 42 = 258

3. Max Loss occurs at = Lower strike price

4. Lower Breakeven point = Lower strike – Max loss

a. 7200 – 258 = 6942

5. Upper breakeven point = Lower strike + Max loss

a. 7200 + 258 = 7458

9.4 – Delta, strike selection, and effect of volatility

As we know, the strategy gets more profitable as and when the market falls. In other

words this is a directional strategy (profitable when markets go down) and therefore the

delta at overall strategy level should reflect this. Let us do the math to figure this out –

 7500 PE is ITM option, delta is - 0.55. However since we have written the option,

the delta is –(-0.55) = +0.55

 7200 PE is OTM, has a delta of - 0.29, remember we are long two lots here

 The overall position delta would be +0.55 + (-0.29) +(-0.29) = - 0.03

The non zero Delta value clearly indicates that the strategy is sensitive to the directional

movement (although negligible). The negative sign indicates that the strategy makes

money when the market goes down.

As far as the strikes are concerned, I’d suggest you stick to the classic combination of

ITM and OTM options. Remember the trade needs to be executed for a ‘Net Credit’. Do

not initiate this strategy if there is a net outflow of cash at the time of execution.

Let’s look at the variation in volatility and its effect on the strategy –

There are three colored lines depicting the change of “premium value” versus change in

volatility. These lines help us understand the effect of increase in volatility on the

strategy keeping time to expiry in perspective.

1. Blue Line – This line suggests that an increase in volatility when there is ample

time to expiry (30 days) is beneficial for the Put ratio back spread. As we can see

the strategy payoff increases from -57 to +10 when the volatility increase from

15% to 30%. Clearly this means that when there is ample time to expiry, besides

being right on the direction of stock/index you also need to have a view on

volatility. For this reason, even though I’m bearish on the stock, I would be a bit

hesitant to deploy this strategy at the start of the series if the volatility is on the

higher side (say more than double of the usual volatility reading)

2. Green line - This line suggests that an increase in volatility when there are

about 15 days time to expiry is beneficial, although not as much as in the previous

case. As we can see the strategy payoff increases from -77 to -47 when the

volatility increase from 15% to 30%.

zerodha.com/varsity

3. Red line – Clearly increase in volatility when we have a few days to expiry does

not have much impact on the premium value. This means, when you are close to

expiry you only need to worry about the directional movement and need not

really worry much about the variation in volatility.

Key takeaways from this chapter

1. The Put Ratio Back spread is best executed when your outlook on the stock/index

is bearish

2. The strategy requires you to sell 1 ITM PE and buy 2 OTM PE, and this is to be

executed in the same ratio i.e for every 1 option sold, 2 options have to be

purchased

3. The strategy is usually executed for a ‘Net Credit’

4. The strategy makes limited money if the stock price goes up, and unlimited profit

when the stock price goes down

5. There are two break even points – lower breakeven and upper breakeven

6. Spread = Higher Strike – Lower Strike

7. Net Credit = Premium Received for Higher strike – 2*Premium paid for lower

strike

8. Max Loss = Spread – Net Credit

9. Max Loss occurs at = Lower Strike

10. The payoff when market goes up = Net Credit

11. Lower Breakeven = Lower Strike – Max Loss

12. Upper Breakeven = Lower Strike + Max Loss

13. Irrespective of the time to expiry opt for ITM and OTM strike combination

14. Increase in volatility is good for this strategy when there is more time to expiry

CHAPTER 10

The Long Straddle

10.1 – The directional dilemma

How many times have you been in a situation wherein you take a trade after much

conviction, either long or short and right after you initiate the trade the market moves

just the other way round? All your strategy, planning, efforts, and capital go for a toss.

I’m certain this is one situation all of us have been in. In fact this is one of the reasons

why most professional traders go beyond the regular directional bets and set up

strategies which are insulated against the unpredictable market direction. Strategies

whose profitability does not really depend on the market direction are called “Market

Neutral” or “Delta Neutral” strategies. Over the next few chapters we will understand

some of the market neutral strategies and how a regular retail trader can execute such

strategies. Let us begin with a ‘Long Straddle’.

100

zerodha.com/varsity

10.2 – Long Straddle

Long straddle is perhaps the simplest market neutral strategy to implement. Once

implemented, the P&L is not affected by the direction in which the market moves. The

market can move in any direction, but it has to move. As long as the market moves

(irrespective of its direction), a positive P&L is generated. To implement a long straddle

all one has to do is –

1. Buy a Call option

2. Buy a Put option

Ensure –

1. Both the options belong to the same underlying

2. Both the options belong to the same expiry

3. Belong to the same strike

Here is an example which explains the execution of a long straddle and the eventual

strategy payoff. As I write this, the market is trading at 7579, which would make the

strike 7600 ‘At the money’. Long straddle would require us to simultaneously purchase

101

zerodha.com/varsity

the ATM call and put options.As you can see from the snapshot above, 7600CE is

trading at 77 and 7600 PE is trading at 88. The simultaneous purchase of both these

options would result in a net debit of Rs.165. The idea here is – the trader is long on

both the call and put options belonging to the ATM strike. Hence the trader is not really

worried about which direction the market would move. If the market goes up, the trader

would expect to see gains in Call options far higher than the loss made (read premium

paid) on the put option. Similarly, if the market goes down, the gains in the Put option

far exceeds the loss on the call option. Hence irrespective of the direction, the gain in

one option is good enough to offset the loss in the other and still yield a positive P&L.

Hence the market direction here is meaningless. Let us break this down further and

evaluate different expiry scenarios. Scenario 1 – Market expires at 7200, put

option makes money This is a scenario where the gain in the put option not only

offsets the loss made in the call option but also yields a positive P&L over and above. At

7200 –

 7600 CE will expire worthless, hence we lose the premium paid i.e Rs. 77

 7600 PE will have an intrinsic value of 400. After adjusting for the premium paid

i.e Rs.88, we get to retain 400 – 88 = 312

 The net payoff would be 312 – 77 = + 235

As you can see, the gain in put option after adjusting for the premium paid for put

option and after adjusting for the premium paid for the call option still yields a positive

P&L. Scenario 2 – Market expires at 7435 (lower breakeven) This is a situation

where the strategy neither makes money nor loses any money.

 7600 CE would expire worthless; hence the premium paid has to be written off.

Loss would be Rs.77

 7600 PE would have an intrinsic value of 165, hence this is the gain in the put

option

 However the net premium paid for the call and put option is Rs.165, which gets

adjusted with the gain in the put option

If you think about it, with respect to the ATM strike, market has indeed expired at a

lesser value. So therefore the put option makes money. However, the gains made in the

put option adjusts itself against the premium paid for both the call and put option,

eventually leaving no money on the table. Scenario 3 – Market expires at 7600 (at

102

zerodha.com/varsity

the ATM strike) At 7600, the situation is quite straight forward as both the call and

put option would expire worthless and hence the premium paid would be gone. The loss

here would be equivalent to the net premium paid i.e Rs.165. Scenario 4 – Market

expires at 7765 (upper breakeven) This is similar to the 2

scenario we discussed.

This is a point at which the strategy breaks even at a point higher than the ATM strike.

 7600 CE would have an intrinsic value of 165, hence this is the gain in Call option

 7600 PE would expire worthless, hence the premium paid towards the option is

lost

 The gain made in the 7600 CE is offset against the combined premium paid

Hence the strategy would breakeven at this point. Scenario 5 – Market expires at

8000, call option makes money Clearly the market in this scenario is way above the

7600 ATM mark. The call option premiums would swell, so much so that the gains in

call option will more than offset the premiums paid. Let us check the numbers –

 7600 PE will expire worthless, hence the premium paid i.e Rs.88 is to be written

off

 At 8000, the 7600 CE will have an intrinsic value of 400

 The net payoff here is 400 – 88 – 77 = +235

103

zerodha.com/varsity

So as you can see, the gain in call option is significant enough to offset the combined

premiums paid. Here is the payoff table at different market expiry levels.As you can

observe –

1. The maximum loss (165) occurs at 7600, which is the ATM strike

2. The profits are unlimited in either direction of the market

104

zerodha.com/varsity

We can visualize these points in the payoff structure here –

From

the V shaped payoff graph, the following things are quite clear –

1. With reference to the ATM strike, the strategy makes money in either direction

2. Maximum loss is experienced when markets don’t move and stay at ATM

a. Max loss = Net premium paid

3. There are two breakevens – on either side, equidistant from ATM

a. Upper Breakeven = ATM + Net premium

b. Lower Breakeven = ATM – Net premium

I’m certain, you find this strategy quite straight forward to understand and implement.

In summary, you buy calls and puts, each leg has a limited down side, hence the

combined position also has a limited downside and an unlimited profit potential. So in

essence, a long straddle is like placing a bet on the price action each-way - you make

money if the market goes up or down. Hence the direction does not matter here. But let

me ask you this – if the direction does not matter, what else matters for this strategy?

10.3 – Volatility Matters

Yes, volatility matters quite a bit when you implement the straddle. I would not be

exaggerating if I said that volatility makes or breaks the straddle. Hence a fair

105

zerodha.com/varsity

assessment on volatility serves as the backbone for the straddle’s success. Have a look at

this graph below –The y-axis represents the cost of the strategy, which is simply the

combined premium of both the options and the x-axis represents volatility. The blue,

green, and red line represents how the premium increases when the volatility increases

given that there is 30, 15, and 5 days to expiry respectively. As you can see, this is a

linear graph and irrespective of time to expiry, the strategy cost increases as and when

the volatility increases. Likewise the strategy costs decreases when the volatility

decreases. Have a look at the blue line; it suggests when volatility is 15%, the cost of

setting up a long straddle is 160. Remember the cost of a long straddle represents the

combined premium required to buy both call and put options. So at 15% volatility it

costs Rs.160 to set up the long straddle, however keeping all else equal, when volatility

increases to 30% it costs Rs.340 to set up the same long straddle. In other words, you

are likely to double your money in the straddle provided –

1. You set up the long straddle at the start of the month

2. The volatility at the time of setting up the long straddle is relatively low

3. After you set up the long straddle, the volatility doubles

You can make similar observations with the green and red line which represents the

‘price to volatility’ behavior when the time to expiry is 15 and 5 days respectively. Now,

this also means you will lose money if you execute the straddle when the volatility is

106

zerodha.com/varsity

high which starts to decline after you execute the long straddle. This is an extremely

crucial point to remember. At this point, let us have a quick discussion on the

overall strategy’s delta. Since we are long on ATM strike, the delta of both the options is

close to 0.5.

 The call option has a delta of + 0.5

 The put option has a delta of - 0.5

The delta of call option offsets the delta of put option thereby resulting in a net ‘0’

overall delta. Recall, delta shows the direction bias of the position. A +ve delta indicates

a bullish bias and a -ve delta indicates a bearish bias. Given this, a 0 delta indicates that

there is no bias whatsoever to the direction of the market. So all strategies which have

zero deltas are called ‘Delta Neutral’ and Delta Neutral strategies are insulated against

the market direction.

10.4 – What can go wrong with the straddle?

On the face of it a long straddle looks great. Think about it – you get to make money

whichever way the market decides to move. All you need is the right volatility estimate.

Therefore, what can really go wrong with a straddle? Well, two things come in between

you and the profitability of a long straddle –

1. Theta Decay – All else equal, options are depreciating assets and this

particularly hurts long positions. The closer you get to expiration, the lesser time

value of the option. Time decay accelerates exponentially during the last week

before expiration, so you do not want to hold onto out-of-the-money or at-the-

money options into the last week and lose premiums rapidly.

2. Large breakevens – Recollect, in the example we discussed earlier, the

breakeven points were 165 points away from the ATM strike. The lower

breakeven point was 7435 and the upper breakeven was 7765, considering the

ATM strike was 7600. In percentage terms, the market has to move 2.2% (either

ways) to achieve breakeven. This means that from the time you initiate the

straddle, the market or the stock has to move atleast 2.2% either ways for you to

start making money…and this move has to happen within a maximum of 30 days.

Further if you want to make a profit of atleast 1% on this trade, then we are

talking about a 1% move over and above 2.2% on the index. Such large move on

107

zerodha.com/varsity

the index is quite a challenge in my opinion and I will explain why in the next

chapter.

Keeping the above two points plus the impact on volatility in perspective, we can

summarize what really needs to work in your favor for the straddle to be profitable -

1. The volatility should be relatively low at the time of strategy execution

2. The volatility should increase during the holding period of the strategy

3. The market should make a large move – the direction of the move does not

matter

4. The expected large move is time bound, should happen quickly – well within the

expiry

From my experience trading long straddles, they are profitable when setup around

major market events and the impact of such events should exceed over and above what

the market expects. Let me explain the ‘event and expectation’ part a bit more, please do

read the following carefully. Let us take the Infosys results as an example here. Event -

Quarterly results of Infosys Expectation – ‘Muted to flat’ revenue guideline for the

coming few quarters. Actual Outcome – As expected Infosys announces ‘muted to flat’

revenue guideline for the coming few quarters. If you were the set up a long straddle in

the backdrop of such an event (and its expectation), and eventually the expectation is

matched, then chances are that the straddle would fall apart. This is because around

major events, volatility tends to increase which tends to drive the premium high. So if

you are to buy ATM call and put options just around the corner of an event, then you are

essentially buying options when the volatility is high. When events are announced and

the outcome is known, the volatility drops like a ball, and therefore the premiums. This

naturally breaks the straddle down and the trader would lose money owing to the

‘bought at high volatility and sold at low volatility’ phenomena. I’ve noticed this

happening over and over again, and unfortunately have seen many traders lose money

exactly for this reason. Favorable Outcome – However imagine, instead of ‘muted to

flat’ guideline they announce an ‘aggressive’ guideline. This would essentially take the

market by surprise and drive premiums much higher, resulting in a profitable straddle

trade. This means there is another angle to straddles – your assessment of the event’s

outcome should be couple of notches better than the general market’s assessment. You

cannot setup a straddle with a mediocre assessment of events and its outcome. This may

seem like a difficult proposition but you will have to trust me here – few quality years of

108

zerodha.com/varsity

trading experience will actually get you to assess situations way better than the rest of

the market. So, just for clarity, I’d like to repost all the angles which need to be aligned

for the straddle to be profitable –

1. The volatility should be relatively low at the time of strategy execution

2. The volatility should increase during the holding period of the strategy

3. The market should make a large move – the direction of the move does not

matter

4. The expected large move is time bound, should happen quickly – well within the

expiry

5. Long straddles are to be set around major events, and the outcome of these

events to be drastically different from the general market expectation.

You may be wondering there are far too many points that come in between you and the

long straddle’s profitability. But worry not, I’ll share an antidote in the next chapter –

The Short Straddle, and why it makes sense. Download the long straddle excel.

Key takeaways from this chapter

1. Strategies which are insulated to market direction are called ‘Market Neutral’ or

‘Delta neutral’

2. Market neutral strategies such as long straddle makes money either which way

the market moves

3. Long straddle requires you to simultaneously buy the ATM Call and Put option.

The options should belong to the same underlying, same strike, and same expiry

4. By buying the CE and PE – the trader is placing the bet on either direction

5. The maximum loss is equal to the net premium paid, and it occurs at the strike at

which the long straddle has been initiated

6. The upper breakeven is ‘strike + net premium’. The lower breakeven is ‘strike –

net premium’

7. The deltas in a long straddle adds up to zero

8. The volatility should be relatively low at the time of strategy execution

9. The volatility should increase during the holding period of the strategy

10. The market should make a large move – the direction of the move does not

matter

CHAPTER 11

The Short Straddle

11.1 – Context

In the previous chapter we understood that for the long straddle to be profitable, we

need a set of things to work in our favor, reposting the same for your quick reference –

1. The volatility should be relatively low at the time of strategy execution

2. The volatility should increase during the holding period of the strategy

3. The market should make a large move – the direction of the move does not

matter

4. The expected large move is time bound, should happen quickly – well within the

expiry

5. Long straddles are to be setup around major events, and the outcome of these

events to be drastically different from the general market expectation.

Agreed that the directional movement of the market does not matter in the long

straddle, but the bargain here is quite hard. Considering the 5 points list, getting the

long straddle to work in you favor is quite a challenge. Do recall, in the previous chapter

the breakdown was at 2%, add to this another 1% as desired profits and we are

essentially looking for, at least a 3% move on the index. From my experience expecting

the market to make such moves regularly is quite a challenge. In fact for this reason

alone, I think twice each and every time I need to initiate a long straddle.

I have witnessed many traders recklessly set up long straddles thinking they are

insulated to the market’s directional movement. But in reality they end up losing money

in a long straddle – time delay and the general movement in the market (or the lack of

it) works against them. Please note, I’m not trying to discourage you from employing the

long straddle, no one denies the simplicity and elegance of a long straddle. It works

extremely well when all the 5 points above are aligned. My only issue with long straddle

is the probability of these 5 points aligning with each other.

111

zerodha.com/varsity

Now think about this – there are quite a few factors which prevents the long straddle to

be profitable. So as an extension of this – the same set of factors ‘should’ favor the

opposite of a long straddle, i.e the ‘Short Straddle’.

11.2 – The Short Straddle

Although many traders fear the short straddle (as losses are uncapped), I personally

prefer trading the short straddle on certain occasions over its peer strategies. Anyway let

us quickly understand the set up of a short straddle, and how its P&L behaves across

various scenarios.

Setting up a short straddle is quite straight forward – as opposed to buying the ATM Call

and Put options (like in long straddle) you just have to sell the ATM Call and Put option.

Obviously the short strategy is set up for a net credit, as when you sell the ATM options,

you receive the premium in your account.

Here is any example, consider Nifty is at 7589, so this would make the 7600 strike ATM.

The option premiums are as follows –

112

zerodha.com/varsity

 7600 CE is trading at 77

 7600 PE is trading at 88

So the short straddle will require us to sell both these options and collect the net

premium of 77 + 88 = 165.

Please do note – the options should belong to the same underlying, same expiry, and of

course same strike. So assuming you have executed this short straddle, let’s figure out

the P&L at various market expiry scenarios.

Scenario 1 – Market expires at 7200 (we lose money on put option)

This is a scenario where the loss in the put option is so large that it eats away the

premium collected by both the CE and PE, resulting in an overall loss. At 7200 –

 7600 CE will expire worthless, hence we get the retain the premium received

i.e 77

 7600 PE will have an intrinsic value of 400. After adjusting for the premium

received i.e Rs.88, we lose 400 – 88 = - 312

 The net loss would be 312 – 77 = - 235

As you can see, the gain in call option is offset by the loss in the put option.

Scenario 2 – Market expires at 7435 (lower breakdown)

This is a situation where the strategy neither makes money nor loses any money.

 7600 CE would expire worthless; hence the premium received is retained. Profit

here is Rs.77

 7600 PE would have an intrinsic value of 165, out of which we have received

Rs.88 as premium, hence our loss would be 165 – 88 = -77

 The gain in the call option is completely offset by the loss in the put option.

Hence we neither make money nor lose money at 7435.

Scenario 3 – Market expires at 7600 (at the ATM strike, maximum profit)

This is the most favorable outcome for a short straddle. At 7600, the situation is quite

straight forward as both the call and put option would expire worthless and hence the

113

zerodha.com/varsity

premium received from both the call and put option will be retained. The gain here

would be equivalent to the net premium received i.e Rs.165.

So this means, in a short straddle you make maximum money when the markets don’t

move!

Scenario 4 – Market expires at 7765 (upper breakdown)

This is similar to the 2

scenario we discussed. This is a point at which the strategy

breaks even at a point higher than the ATM strike.

 7600 CE would have an intrinsic value of 165, hence after adjusting for the

premium received of Rs. 77, we stand to lose Rs.88 (165 – 77)

 7600 PE would expire worthless, hence the premium received i.e Rs.88 is

retained

 The gain made in the 7600 PE is offset against the loss on the 7600 CE, hence we

neither make money nor lose money.

Clearly this is the upper breakdown point.

Scenario 5 – Market expires at 8000 (we lose money on call option)

Clearly the market in this scenario is way above the 7600 ATM mark. The call option

premium would swell, so would the loss –

 7600 PE will expire worthless, hence the premium received i.e Rs.88 is retained

 At 8000, the 7600 CE will have an intrinsic value of 400, hence after adjusting

for the premium received of Rs. 77, we stand to lose Rs. 323( 400 -77)

 We have received Rs.88 as premium for the Put option, therefore the loss would

be 88- 323 = -235

So as you can see, the loss in the call option is significant enough to offset the combined

premiums received.

Here is the payoff table at different market expiry levels.

114

zerodha.com/varsity

As you can observe –

1. The maximum profit 165 occurs at 7600, which is the ATM strike

2. The strategy remains profitable only between the lower and higher breakdown

numbers

3. The losses are unlimited in either direction of the market

We can visualize these points in the payoff structure here –

From the inverted V shaped payoff graph, the following things are quite clear –

115

zerodha.com/varsity

1. The point at which you can experience maximum profits is at ATM, the profits

shrink as you move away from the ATM mark

2. The strategy is profitable as long as the market stays within the breakdown points

3. Maximum loss is experienced when markets move further away from the

breakdown point. The further away the market moves from the breakdown point,

higher the loss

a. Max loss = Unlimited

4. There are two breakdown points – on either side, equidistant from ATM

a. Upper Breakdown = ATM + Net premium

b. Lower Breakdown = ATM – Net premium

116

As you may have realized by now, the short straddle works exactly opposite to the long

straddle. Short straddle works best when markets are expected to be in a range and not

really expected to make a large move.

Many traders fear short straddle considering the fact that short straddles have unlimited

losses on either side. However from my experience, short straddles work really well if

you know how exactly to deploy this. In fact in the last chapter of the previous module, I

had posted a case study involving short straddle. Probably that was one of the best

examples of when to implement the short straddle.

I will repost the same again here and I hope you will be able to appreciate the case study

better.

11.3 – Case Study (repost from previous module)

The following case study was a part of Module 5, Chapter 23. I’m reposting the same

here as I assume you would appreciate the example better at this stage. To get the

complete context, I’d request you to read the chapter.

Infosys was expected to announce their Q2 results on 12

October. The idea was simple

– news drives volatility up, so short options with an expectation that you can buy it back

when the volatility cools off. The trade was well planned and the position was initiated

on 8

Oct - 4 days prior to the event.

Infosys was trading close to Rs.1142/- per share, so he decided to go ahead with the 1140

strike (ATM).

Here is the snapshot at the time of initiating the trade -

117

zerodha.com/varsity

On 8

October around 10:35 AM the 1140 CE was trading at 48/- and the implied

volatility was at 40.26%. The 1140 PE was trading at 47/- and the implied volatility was

at 48%. The combined premium received was 95 per lot.

Market’s expectation was that Infosys would announce fairly decent set of numbers. In

fact the numbers were better than expected, here are the details -

“For the July-September quarter, Infosys posted a net profit of $519 million, compared

with $511 million in the year-ago period. Revenue jumped 8.7 % to $2.39 billion. On a

sequential basis, revenue grew 6%, comfortably eclipsing market expectations of 4- 4.5%

growth.

In rupee terms, net profit rose 9.8% to Rs.3398 crore on revenue of Rs. 15,635 crore,

which was up 17.2% from last year”. Source: Economic Times.

118

zerodha.com/varsity

The announcement came in around 9:18 AM, 3 minutes after the market opened, and

this trader did manage to close the trade around the same time.

Here is the snapshot -

The 1140 CE was trading at 55/- and the implied volatility had dropped to 28%. The

1140 PE was trading at 20/- and the implied volatility had dropped to 40%.

Do pay attention to this - the speed at which the call option shot up was

lesser than the speed at which the Put option dropped its value. The

combined premium was 75 per lot, and he made a 20 point profit per lot.

119

zerodha.com/varsity

11.4 – The Greeks

Since we are dealing with ATM options, the delta of both CE and PE would be around

0.5. We could add the deltas of each option and get a sense of how the overall position

deltas behave.

 7600 CE Delta @ 0.5, since we are short, the delta would be -0.5

 7600 PE Delta @ - 0.5, since we are short, the delta would be + 0.5

 Combined delta would be -0.5 + 0.5 = 0

The combined delta indicates that the strategy is directional neutral. Remember both

long and short straddle is delta neutral. In case of long straddle, delta neutral suggests

that the profits are uncapped and in case of short straddle, the losses are uncapped.

Now here is something for you to think about – When you initiate a straddle you are

obviously delta neutral. But as the markets move, will your position still remain delta

neutral? If yes, why do you think so? If no, then is there a way to keep the position delta

neutral?

If you can build your thoughts around these points, then I can guarantee you that your

options knowledge is far greater than 90% of the market participants. To answer these

simple questions, you will need to step a little deeper and get into 2

level of thinking.

Key takeaways from this chapter

1. Short straddle requires you to simultaneously Sell the ATM Call and Put option.

The options should belong to the same underlying, same strike, and same expiry

2. By selling the CE and PE – the trader is placing the bet that the market wont

move and would essentially stay in a range

3. The maximum profit is equal to the net premium paid, and it occurs at the strike

at which the long straddle has been initiated

120

4. The upper breakdown is ‘strike + net premium’. The lower breakdown is ‘strike –

net premium’

5. The deltas in a short straddle adds up to zero

6. The volatility should be relatively high at the time of strategy execution

7. The volatility should decrease during the holding period of the strategy

8. Short straddles can be set around major events, wherein before the event, the

volatility would drive the premiums up and just after the announcement, the

volatility would cool off, and so would the premiums.

CHAPTER 12

The Long & Short Straddle

12.1 – Background

If you have understood the straddle, then understanding the ‘Strangle’ is quite

straightforward. For all practical purposes, the thought process behind the straddle and

strangle is quite similar. Strangle is an improvisation over the straddle, mainly to reduce

the cost of implementation. Let me explain this further.

Consider this – Nifty is trading at 5921, which would make 5900 the ATM strike. If you

were to set up the long straddle here, you would be required to buy the 5900 CE and

5900 PE. The premiums for both these options are 66 and 57 respectively.

Net cash outlay = 66 + 57 = 123

Upper breakeven = 5921+123 = 6044

Lower breakeven = 5921 – 123 = 5798

Therefore to set up a straddle, you spend 123 and the breakeven on either side is 2.07%

away. As you know the straddle is delta neutral, meaning the strategy is insulated to the

directional movement of the market. The idea here is that you know that the market will

move to a large extent, but the direction is unknown.

Consider this – from your research you know that the market will move (direction

unknown) hence you have set up the straddle. However the straddle requires you to

make an upfront payment of 123.

How would it be if you were to set up a market neutral strategy - similar to the straddle,

but at a much lower cost?

Well, the ‘Strangle’ does just that.

122

12.2 – Strategy Notes

The strangle is an improvisation over the straddle. The improvisation mainly helps in

terms of reduction of the strategy cost, however as a tradeoff the points required to

breakeven increases.

In a straddle you are required to buy call and put options of the ATM strike. However

the strangle requires you to buy OTM call and put options. Remember when compared

to the ATM strike, the OTM will always trade cheap, therefore this implies setting up a

strangle is cheaper than setting up a straddle.

Let’s take an example to explain this better –

Nifty is trading at 7921, to set up a strangle we need to buy OTM Call and Put options.

Do note, both the options should belong to the same expiry and same underlying. Also

the execution should happen in the same ratio (missed this point while discussing

straddle).

123

zerodha.com/varsity

Same ratio here means – one should buy the same number of call option as that of put

option. For instance it can be 1:1 ratio meaning 1 lot of call, 1 lot of put option. Or it can

be 5:5, meaning buy 5 lots of call and 5 lots of put option. Something like 2:3 is not

considered strangle (or straddle) as in this case you would be buying 2 lots of call

options and 3 lots of put options.

Going back to the example, considering Nifty is at 5921, we need to buy OTM Call and

Put options. I’d prefer to buy strikes which are 200 points either way (note, there is no

particular reason for choosing strikes 200 points away). So this would mean I would buy

7700 Put option and 8100 Call option. These options are trading at 28 and 32

respectively.

The combined premium paid to execute the ‘strangle’ is 60. Let’s figure out how the

strategies behave under various scenarios. I’ll keep this discussion brief as I do believe

you are now comfortable accessing the P&L across various market scenarios.

Scenario 1 – Market expires at 7500 (much below the PE strike)

At 7500, the premium paid for the call option i.e. 32 will go worthless. However the put

option will have an intrinsic value of 200 points. The premium paid for the Put option is

28, hence the total profit from the put option will be 200 – 28 = +172

We can further deduct for the premium paid for call option i.e. 32 from the profits of Put

option and arrive at the overall profitability i.e. 172 – 32 = +140

Scenario 2 – Market expires at 7640 (lower breakeven)

At 7640, the 7700 put option will have an intrinsic value of 60. The put option’s intrinsic

value offsets the combined premium paid towards both the call and put option i.e.

32+28 = 60. Hence at 7640, the strangle neither makes money nor losses money.

Scenario 3 – Market expires at 7700 (at PE strike)

At 7700, both the call and put options would expire worthless, hence we would lose the

entire premium paid i.e. 32 + 28 = 60. Do note, this also happens to be the maximum

loss the strategy would suffer.

Scenario 4 – Market expires at 7900, 8100 (ATM and CE strike respectively)

124

zerodha.com/varsity

Both the options expire worthless at 7900 and 8100. Hence we would lose the entire

premium paid i.e. 60.

Scenarios 5 – Market expires at 8160 (upper breakeven)

At 8160, the 8100 Call option has an intrinsic value of 60, the gains in the call option

would offset the loss incurred against the premium paid towards the call and put

options.

Scenarios 6 – Market expires at 8300 (much higher than the CE strike)

Clearly at 8300, the 8100 call option would have an intrinsic value of 200 points;

therefore the option would make 200 points. After adjusting for the combined premium

paid of 60 points, we would be left with 140 points profit. Notice the symmetry of payoff

above the upper and below the lower breakeven points.

Here is a table which contains various other market expiry scenarios and the eventual

payoff at these expiry levels –

We can plot the strategy payoff to visualize the payoff diagram of the strangle –

125

zerodha.com/varsity

We can generalize a few things about the ‘Strangle’ –

1. The maximum loss is restricted to the net premium paid

2. The loss would be maximum between the two strike prices

3. Upper Breakeven point = CE strike + net premium paid

4. Lower Breakeven point = PE strike – net premium paid

5. Profit potentially is unlimited

So as long as the market moves (irrespective of the direction) the profits are expected to

follow.

12.3 – Delta and Vega

Both straddles and strangles are similar strategies, therefore the Greeks have a similar

effect on strangle and straddles.

Since we are dealing with OTM options (remember we chose strikes that are equidistant

from ATM), the delta of both CE and PE would be around 0.3, or lesser. We could add

the deltas of each option and get a sense of how the overall position deltas behave.

 7700 PE Delta @ - 0.3

 8100 CE Delta @ + 0.3

 Combined delta would be -0.3 + 0.3 = 0

126

zerodha.com/varsity

Of course, I’ve just assumed 0.3 for both the options for convenience; however both the

deltas could be slightly different, hence we could not be delta neutral in a strict sense.

But then the deltas will certainly not be too high such that it renders a directional bias

on the strategy. Anyway, the combined delta indicates that the strategy is directional

neutral.

The volatility has similar effect on both straddles and strangles. I’d suggest you

refer Chapter 10, section 10.3 to get a sense of how the volatility impacts the

strangles.

To summarize the effect of Greeks on strangles -

1. The volatility should be relatively low at the time of strategy execution

2. The volatility should increase during the holding period of the strategy

3. The market should make a large move – the direction of the move does not

matter

4. The expected large move is time bound, should happen quickly – well within the

expiry

5. Long strangle is to be setup around major events, and the outcome of these

events have to be drastically different from the general market expectation

I suppose you understand why long strangles have to be set up around major market

events; we have discussed this point earlier as well. If you are confused, I’d request you

to read Chapter 10.

12.4 – Short Strangle

The execution of a short strangle is the exact opposite of the long strangle. One needs to

sell OTM Call and Put options which are equidistant from the ATM strike. In fact you

would short the ‘strangle’ for the exact opposite reasons as to why you go long strangle. I

will skip discussing the different expiry scenarios as I assume you are fairly comfortable

with establishing the payoff by now.

I’ve used the same strikes (the one used in long strangle example) for the short strangle

example. Instead of buying these options, you would sell these OTM options to set up a

short strangle. Here is the payoff table of the short strangle –

127

zerodha.com/varsity

As you can notice, the strategy results in a loss as and when the market moves in any

particular direction. However the strategy remains profitable between the lower and

upper breakeven points. Recall –

 Upper breakeven point is at 8160

 Lower breakeven point is at 7640

 Max profit is net premium received, which is 60 points

In other words you get to take home 60 points as long as the market stays within 7640

and 8160. In my opinion this is a fantastic proposition. More often than not market

stays within certain trading ranges and therefore the market presents such beautiful

trading opportunities.

So here is something for you to think about – identify stocks which are in a trading

range, typically stocks in a trading range form double/triple tops and bottom. Setup the

‘strangle’ by writing strikes which are outside the upper and lower range. When you

write strangles in this backdrop make sure you watch closely for breakouts or

breakdowns.

I remember setting up this trade over and over again in Reliance couple of years ago -

Reliance was stuck between 850 and 1000 for the longest time.

128

zerodha.com/varsity

Anyway, here is the payoff graph of the short strangle –

As you can notice –

1. The payoff of the short strangle looks exactly opposite of the long strangle

2. The profits are restricted to the extent of the net premium received

3. The profits are maximum as long as the stock stays within the two strike prices

4. The losses are potentially unlimited

The breakeven point calculation is the same as the breakeven points of a long strangle,

which we have discussed earlier.

Key takeaways from this chapter

1. The strangle is an improvisation over the straddle, the improvisation helps in the

strategy cost reduction

2. Strangles are delta neutral and is insulated against any directional risk

3. To set up a long strangle one needs to buy OTM Call and Put option

4. The maximum loss in a long strangle is restricted to the extent of the premium

received

5. The profit potential is virtually unlimited in the long strangle

129

6. The short strangle is the exact opposite of the long strangle. You are required to

sell the OTM call and put option in a short strangle

7. The Greeks have the same effect on strangles and straddles

CHAPTER 13

Max Pain & PCR

13.1 – My experience with Option Pain theory

In the never ending list of controversial market theories, the theory of ‘Option Pain’

certainly finds a spot. Option Pain, or sometimes referred to as ‘Max Pain’ has a

significant fan following and probably an equal number of people who despise it. I’ll be

honest; I’ve been in both camps! In the initial days of following Option Pain, I was never

able to make money consistently. However, overtime I found methods to improvise on

this theory to suit my own risk appetite, and that yielded a decent result. Later in the

chapter I will discuss this as well.

Anyway, now this is my attempt to present you the Option Pain theory and talk to you

about what I like and what I don’t about Max Pain. You can take cues from this chapter

and decide for yourself which camp you want to be in.

Option Pain theory requires you to be familiar with the concept of ‘Open Interest’.

So, let’s get started.

13.2 – Max Pain Theory

The origins of Option Pain dates back to 2004. So, in a sense, this is still a very young

theory. As far as I know there are no academic/scholastic papers on it, which makes one

wonder why the academia has ignored this concept.

The theory of options pain stems as a corollary to the belief - “90% of the options expire

worthless, hence option writers/sellers tend to make money more often, more

consistently than the option buyers”.

Now if this statement is true, then we can make a bunch of logical deductions -

131

zerodha.com/varsity

1. At any point only one party can make money i.e either the option buyers or

option sellers, but not both. From the above statement, it is clear that the sellers

are the ones making money.

2. If option sellers tend to make maximum money, then it also means that the price

of the option on expiry day should be driven to a point where it would cause least

amount of loss to option writers.

3. If point 2 is true, then it further implies that option prices can be manipulated, at

least on the day of expiry.

4. If point 3 is true, then it further implies that there exists a group of traders who

can manipulate the option prices, at least on the day of expiry.

5. If such a group exists then it must be the option writers/sellers since it is believed

that they are the ones who make maximum money/consistently make money

trading options.

Now considering all the above points, there must exist a single price point at which, if

the market expires, then it would cause least amount of pain to the option writers (or

cause maximum amount of pain to option buyers).

If one can identify this price point, then it’s most likely that this is the point at which

markets will expire. The ‘Option Pain’ theory does just this – identify the price at which

the market is likely to expire considering least amount of pain is caused to option

writers.

132

zerodha.com/varsity

Here is how optionspain.com formally defines Option Pain – “In the options market,

wealth transfer between option buyers and sellers is a zero sum game. On option

expiration days, the underlying stock price often moves toward a point that brings

maximum loss to option buyers. This specific price, calculated based on all outstanding

options in the markets, is called Option Pain. Option Pain is a proxy for the stock price

manipulation target by the option selling group”.

13.3 – Max Pain Calculation

Here is a step by step guide to calculate the Max Pain value. At this stage, you may find

this a bit confusing, but I recommend you read through it all the same. Things ill get

clearer once we take up an example –

Step 1 – List down the various strikes on the exchange and note down the open interest

of both calls and puts for these strikes.

Step 2 – For each of the strike price that you have noted, assume that the market

expires at that strike.

133

zerodha.com/varsity

Step 3 – Calculate how much money is lost by option writers (both call option and put

option writers) assuming the market expires as per the assumption in step 2.

Step 4 – Add up the money lost by call and put option writers.

Step 5 – Identify the strike at which the money lost by option writers is least.

This level, at which least amount of money is lost by option writers is the point at which

maximum pain is caused to option buyers. Therefore this is the price at which the

market is most likely to expire.

Let us take up a very simple example to understand this. For the sake of this example,

I’ll assume there are only 3 Nifty strikes available in the market. I have made a note of

the open interest for both call and put options for the respective strike.

Strike

Call Option OI

Put option OI

7700

1823400

5783025

7800

3448575

4864125

7900

5367450

2559375

Scenario 1 – Assume markets expires at 7700

Remember when you write a Call option, you will lose money only if the market moves

above the strike. Likewise, when you write a Put option you will lose money only when

the market moves below the strike price.

Therefore if the market expires at 7700, none of the call option writers will lose money.

Which means call option writers of 7700, 7800, and 7900 strikes will retain the

premiums received.

However, the put option writers will be in trouble. Let’s start with the 7900 PE writers –

At 7700 expiry, 7900 PE writers would lose 200 points. Since the OI is 2559375, the

Rupee value of loss would be –

= 200 * 2559375 = Rs.5,11,875,000/-

7800 PE writers would lose 100 points, the Rupee value would be

134

zerodha.com/varsity

= 100 * 4864125 = Rs.4,864,125,000/-

7700 PE writers will not lose any money.

So the combined money lost by option writers if the markets expire at 7700 would be –

Total money lost by Call Option writers + Total money lost by Put Option writers

= 0 + Rs.511875000 + 4,864125000 = Rs.9,98,287,500/-

Keep in mind that total money lost by Call Option writers = money lost by 7700 CE

writer + money lost by 7800 CE + money lost by 7900 CE

Likewise the Total money lost by Put Option writers = money lost by 7700 PE writer +

money lost by 7800 PE + money lost by 7900 PE

Scenario 2 – Assume markets expires at 7800

At 7800, the following call option writers would lose money –

7700 CE writers would lose 100 points, multiplying with its Open Interest we get the

Rupee value of the loss.

100*1823400 = Rs.1,82,340,000/-

Both 7800 CE and 7900 CE seller would not lose money.

The 7700 and 7800 PE seller wouldn't lose money

The 7900 PE would lose 100 points, multiplying with the Open Interest, we get the

Rupee value of the loss.

100*2559375 = Rs.2,55,937,500/-

So the combined loss for Options writers when market expires at 7800 would be –

= 182340000 + 255937500

= Rs.4,38,277,500/-

135

zerodha.com/varsity

Scenario 3 – Assume markets expires at 7900

At 7900, the following call option writers would lose money –

7700 CE writer would lose 200 points, the Rupee value of this loss would be –

200 *1823400 = Rs.3,646,800,000/-

7800 CE writer would lose 100 points, the Rupee value of this loss would be –

100*3448575 = Rs.3,44,857,500/-

7900 CE writers would retain the premiums received.

Since market expires at 7900, all the put option writers would retain the premiums

received.

So therefore the combined loss of option writers would be –

= 3646800000 + 344857500 = Rs. 7,095,375,000/-

So at this stage, we have calculated the total Rupee value loss for option writers at every

possible expiry level. Let me tabulated the same for you –

Strike

Call Option OI

Put option OI

Loss value of calls

Loss value of Puts

Total loss

7700

1823400

5783025

998287500

7800

3448575

4864125

182340000

255937500

438277500

7900

5367450

2559375

7095375000

Now that we have identified the combined loss the option writers would experience at

various expiry level, we can easily identify the point at which the market is likely to

expire.

As per the option pain theory, the market will expire at such a point where there is least

amount of pain (read it as least amount of loss) to Option sellers.

Clearly, from the table above, this point happens to be 7800, where the combined loss is

around 438277500 or about 43.82 Crores, which is much lesser compared to the

combined loss at 7700 and 7900.

136

zerodha.com/varsity

The calculation is as simple as that. However, I’ve used only 3 strikes in the example for

simplicity. But in reality there are many strikes for a given underlying, especially Nifty.

Calculations become a bit cumbersome and confusing, hence one would have to resort

to a tool like excel.

I’ve calculated the option pain value as of today (10

May 2016) on excel, have a look at

the image –

For all the available strikes, we assume market would expire at that point and then

compute the Rupee value of the loss for CE and PE option writers. This value is shown

in the last column titled “Total Value”. Once you calculate the total value, we simply

have to identify the point at which the least amount of money is lost by the option

writer. You can identify this by plotting the ‘bar graph’ of the total value. The bar graph

would look like this –

137

zerodha.com/varsity

As you can see, the 7800 strike is the point at which option writers would lose the least

amount of money, so as per the option pain theory, 7800 is where the market is likely to

expire for the May series.

Now that you have established the expiry level, how can you use this information? Well,

there are multiple ways you can use this information.

Most traders use this max pain level to identity the strikes which they can write. In this

case, since 7800 is the expected expiry level, one can choose to write call options above

7800 or put options below 7800 and collect all the premiums.

13.4 – A Few Modifications

In the initial days, I was very eager to learn about Option Pain. Everything about it made

absolute sense. I remember crunching numbers, identifying the expiry level, and writing

options to glory. But shockingly the market would expire at some other point leaving me

booking a loss and I wondering if I was wrong with my calculations or if the entire

theory is flawed!

So I eventually improvised on the classic option pain theory to suit my risk appetite.

Here is what I did –

1. The OI values change every day. This means the option pain could suggest 7800

as the expiry level on 10

of May and may very well suggest 8000 on 20

of May.

138

zerodha.com/varsity

I froze on a particular day of the month to run this computation. I preferred

doing this when there were 15 days to expiry.

2. I identified the expiry value as per the regular option pain method.

3. I would add a 5% ‘safety buffer’. So at 15 days to expiry, the theory suggest 7800

as expiry, then I’d add a 5% safety buffer. This would make the expiry value as

7800 + 5% of 7800 = 8190 or 8200 strike.

4. I would expect the market to expire at any point between 7800 to 8200.

5. I would set up strategies keeping this expiry range in mind, my most favorite

being to write call options beyond 8200.

6. I would avoid writing Put option for this simple belief – panic spreads faster than

greed. This means markets can fall faster than it can go up.

7. I would hold the options sold up to expiry, and would usually avoid averaging

during this period.

The results were much better when I followed this method. Unfortunately, I never

tabulated the results, hence I cannot quantify my gains. However if you come from a

programming background, you can easily back test this logic and share the results with

the rest of community here. Anyway, at a much later stage I realized the 5% buffer was

essentially taking to strikes which were approximately 1.5 to 2% standard deviations

away, which meant the probability of markets moving beyond the expected expiry level

was about 34%.

If you are not sure what this means, I’d suggest you read this chapter on standard

deviation and distribution of returns.

You can download the Option Pain computation excel.

13.5 – The Put Call Ratio

The Put Call Ratio is a fairly simple ratio to calculate. The ratio helps us identify extreme

bullishness or bearishness in the market. PCR is usually considered a contrarian

indicator. Meaning, if the PCR indicates extreme bearishness, then we expect the market

to reverse, hence the trader turns bullish. Likewise if PCR indicates extreme bullishness,

then traders expect markets to reverse and decline.

139

zerodha.com/varsity

To calculate PCR, all one needs to do is divide the total open interest of Puts by the total

open interest of the Calls. The resulting value usually varies in and around one. Have a

look at the image below –

As on 10

May, the total OI of both Calls and Puts has been calculated. Dividing the Put

OI by Call OI gives us the PCR ratio –

37016925 / 42874200 = 0.863385

The interpretation is as follows –

 If the PCR value is above 1, say 1.3 – then it suggests that there are more Puts

being bought compared to Calls. This suggests that the markets have turned

extremely bearish, and therefore sort of oversold. One can look for reversals and

expect the markets to go up.

 Low PCR values such as 0.5 and below indicates that there are more calls being

bought compared to puts. This suggests that the markets have turned extremely

bullish, and therefore sort of overbought. Once can look for reversals and expect

the markets to go down.

140

zerodha.com/varsity

 All values between 0.5 and 1 can be attributed to regular trading activity and can

be ignored.

Needless to say, this is a generic approach to PCR. What would really make sense is to

historically plot the daily PCR values for say 1 or 2 years and identify these extreme

values. For example for Nifty value such as 1.3 can indicate extreme bearishness, but for

say Infy something like 1.2 could be extreme bearishness. So you need to be clear about

this, hence back testing helps.

You may wonder why the PCR is used as a contrarian indicator. Well, the explanation to

this is rather tricky, but the general opinion is this – if the traders are bearish/bullish,

then most of them have already taken their respective position (hence a high/low PCR)

and therefore there aren’t many other players who can come in and drive the positions

in the desired direction. Hence the position will eventually be squared off which would

drive the stock/index in the opposite direction.

So that’s PCR for you. You may come across many variants of this – some prefer to take

the total traded value instead of OI, some even prefer to take the volumes. But I

personally don’t think it is required to over-think PCR.

13.6 – Final thoughts

And with this, I’d like to end this module on Options, which has spread across 2

modules and 36 chapters!

We have discussed close to 15 different option strategies in this module, which I

personally think is more than sufficient for retail traders to trade options professionally.

Yes, going forward you will encounter many fancy option strategies, perhaps your friend

will suggest a fancy option strategy and show off the technicalities of the strategy, but do

remember – ‘fancy’ does not really translate to profit. Some of the best strategies are

simple , elegant and easy to implement.

The content we have presented in both, Module 5 and Module 6, is written with an

intention of giving you a clear picture on options trading - what is possible to be achieve

with options trading and what is not possible. We have thought through and discussed

what is required and what isn’t. Frankly these two modules are more than sufficient to

answer most of your concerns/doubts related to options.

141

zerodha.com/varsity
